Catch exception and report it when making a network request with invalid URL on Android

Browse Source 
Summary:
Currently if you invoke `fetch()` with an invalid URL ("aaa" for
example) you cannot catch the error in javascript since it's not
reported. Instead the entire app crashes.

Fixes #7436 and #18087

Hopefully.
