The default reaction to configuration changes in Android
is to destroy the activity. To avoid this happening for
locale changes, we had the "locale" configuration change
registered in the default AndroidManifest.xml, however,
you also need to register that you are handling the
layoutDirection change, otherwise Android will not
call onConfigurationChange() for language changes, but
tear down the activity instead.

[ChangeLog][Android] Fixed bug where application was not
resumable after user changed language in system settings.
