Fix deprecated reflection type to string

[mortenscheel]

\ReflectionType::__toString() was deprecated in PHP 7.1.

This PR fixes the issue by using \ReflectionNamedType when the PHP version is >= 7.1.

I've also included a couple of commits with coding standard fixes that are not related to this issue.

Thank you for the contribution! It seems like a great way to keep backwards compatibility with PHP 7.0 (even if it's EOL).
There were some smaller code style issues that I have highlighted.

You were able to test your changes before submitting, right? Sadly I don't have any environment set up right now.

Hi. I've tested it locally in one of my projects, but I'm only able to test with PHP 7.4.
It would be nice to have proper tests, but I don't know if Testbench would work for something like this?

Sadly I'm not familiar with the recent tools and practices in PHP so I couldn't say :/
Nevertheless, if you won't find a great way to test it out extensively, we can release a few feature version with this PR so people can try it out.

Just a status check. Are you happy with the changes I made?

[KristofMorva]

Sorry for the delay. It has been released in https://github.com/KristofMorva/laravel-ide-macros/releases/tag/1.5.0

Thank you for your contribution! :)
Let me know if you experience any issues regarding this solution.

Hello @mortenscheel, it seems to break #21. Could you please make a change which does not use \ for built-in types?

Hi @KristofMorva
Sorry about that. It's fixed in #22
