Compilation errors cause gulp:watch and playground tasks to fail & exit

[txinfo]

If you run the gulp:watch or playground tasks and make a coding error that causes a compilation failure, it stops the watch task and requires a restart. The failure seems to happen in the rollup tasks as the index.js file doesn't exist after ngc failure:

[0] [11:36:43] Starting 'rollup:fesm'...
[0]
[0] events.js:160
[0] throw er; // Unhandled 'error' event

Since I would imagine this is quite a common occurrence, and it is annoying to have to keep restarting your watch/playground task mnually, it would be nice to handle compilation errors more gracefully.

Please do some changes in package.json file
You have to change playground script like that:

    "playground": "concurrently \"npm run build && npm run lite\" \"npm run playground:build\"",

I had similar issue. It resolved my problem.

@txinfo can you please try to use this PR #274 ( or apply the changes ) in your project and see if the problem still persist?
