Subject: [PATCH] Fix crash when ComposeUIConfig.dismiss called after hosting
 controller dealloc'd

I'm not sure how this can happen (possibly if the user dismissed the
compose screen while the status was being posted? but I haven't been
able to reproduce that), but guard against it since it's causing crashes
