Improve output (and suppress GaxiosError) on failed push

[Nu11u5]

Fixes #827, #907

• Suppresses GaxiosError object dump on failed push
• Instead, only error.message is output to the console
• Always calls stopSpinner() before outputting to console
• Only shows project file list and success message when no error is thrown
• Formats syntax error message file path and line number as parsable by IDEs
• Outputs formatted code snippet of the error line

Checklist

• npm run test succeeds.
• npm run lint succeeds.
• Appropriate changes to README are included in PR.

We found a Contributor License Agreement for you (the sender of this pull request), but were unable to find agreements for all the commit author(s) or Co-authors. If you authored these, maybe you used a different email address in the git commits than was used to sign the CLA (login here to double check)? If these were authored by someone else, then they will need to sign a CLA as well, and confirm that they're okay with these being contributed to Google.
In order to pass this check, please resolve this problem and then comment @googlebot I fixed it.. If the bot doesn't comment, it means it doesn't think anything has changed.

Is this interesting contribution blocked just because of a failed CLA detection by google bot ?!
@Nu11u5 can you try to sign with your github e-mail address nu***[email protected] ?

I think I submitted my commit wrong, instead of using @users.noreply.github.com, so GitHub can't associate it with my account. Attempting to fix.

@alex-galey - fixed, thanks for pinging me the reminder.

Recommited with merge conflicts properly resolved. Added syntax error output formatting so that file names and line numbers can be parsed by popular IDEs and linked to the source file. Tested in VS Code.

Is your PR also aims to solve that behavior of clasp not throwing an error when a Gaxios error happens and concluding with a misleading message "Pushed x files." when it didn't successfully push ?

Yes, the success message and file list will now only be output when the push succeeds.

If it fails due to a syntax error detected by GAS, it will return a single line error message that can be automatically linked to the source file/line in an IDE like VS Code.

Any other type of error from GAS will return just the error description instead of dumping everything to the terminal.

@PopGoesTheWza is there a chance this PR is merged or do you see anything else that should be worked on ?

Hi @sqrrrl, is there a chance this PR is merged or do you see anything else that should be worked on ?

[Nu11u5]

@alex-galey thanks for trying to bring attention to this. I had honestly forgotten about this PR. Please share of any additional work should be done.

[alex-galey]

@sqrrrl do you have any insight why this PR is not being merged ?

[tecsoc]

I need this PR for me too.
Why not merge?
