Subject: [PATCH] Work around crash when default colors are null

Summary:
Work around crash in Android TextInput when default colors are null.

This likely indicates that the Context is corrupted in some way, so this is not a permanent solution.

Changelog: [Internal] Raise soft exception is default platform text color isn't defined
