places where it's deemed dangerous to plumb through a transaction without
further scrutiny.
Shows the conversation picker, and sends the attachment to that
conversation.

-[ ] resolve JSQ dependency
-[ ] properly wait for app to load
-[ ] dismiss share extension after send is complete
-[ ] support non jpeg file types
-[ ] Fix device sleep manager
