Increase timeout for startWatcher

[Ritzlgrmft]

Short description of the problem:

Currently my machine is too slow to start the watching of my app in 3 seconds. Therefore ionic serve produces:

...
[10:28:18]  build dev finished in 52.67 s
[10:28:22]  watch failed: A watch configured to watch the following paths failed to start. It likely that a file
            referenced does not exist:
            ...\src\**\*.(ts|html|s(c|a)ss)

What behavior are you expecting?

It should be possible to use ionic serve also if the start of watching needs longer than 3 seconds.

I changed the timeout in node_modules\@ionic\app-scripts\dist\watch.js to 30 seconds.
Then everything worked as expected.

Which @ionic/app-scripts version are you using?
1.1.3

Fixed in 1.1.4, it's now configurable. See the readme for IONIC_START_WATCH_TIMEOUT property.

Thanks,
