fix(android): StringIndexOutOfBoundsException with invalid drawables (#9563)

Browse Source 
* fix(android/application): org.nativescript.widgets.Utils::getDrawable

* chore: fix spacing

* fix(android/application): do not load empty path

Co-authored-by: Igor Randjelovic <rigor789@gmail.com>

* test: Add tests for empty image sources

* chore: add a few more test cases

These make the app crash without the fix in place
