Resolve sendIntent call, reject on exception thrown

Summary:
Promises created from `Linking.sendIntent` calls never resolve, leaving them dangling. This change fixes the issue in two spots:
1. By calling promise.resolve directly after the startActivity call
1. By wrapping startActivity in a try/catch so any exceptions thrown are forwarded to the promise as a rejection

Changelog: [Android][Fixed] - Ensure Linking.sendIntent promises resolve or reject
