Mojo doesn't allow removing an uncalled mojo callback while the message pipe is
still open.

On Android, SpellCheckerSessionBridge::RequestTextCheck() discards an incoming
request if it fails to initialize the Java object. In this case, this patch replies
the request with empty result so Mojo requirements are ensured.
