* Fix broken 2499 test
SelectedIndex being a BP, setting it's value might be delayed, and as
both ios and android PickerRenderer do not update on individual property
changes, but have a single UpdatePicker method, some properties might be
out-of-date, causing a crash.
This doesn't attemps to fix the renderers, but only prevents a crash to
happen.
* [Android] Apply fix to AppCompact picker
* [iOS] Enable linker for sdk
* [UITests] Better test for issue 2499
