AppCompatDelegate - fix cast exception

View#getParent can return a ViewParent and not
necessarily a View. Check that the action mode view
is an instance of View (besides checking for null)
before casting it to a View.

Test: create a custom dialog with TextView as message,
open it and select text multiple times. Observe no crash.
