android: fix crash when requesting permissions

The RN Permissions module calls this in a non-UI thread. What we observe is a
crash in ViewGroup.dispatchCancelPendingInputEvents, which is called on the
calling (ie, non-UI) thread. This doesn't look very safe, so try to avoid a
crash by pretending the permission was denied.
