Quicksand - fix project board page and quicksand

Summary: Fixes T7913. Collapse the separate board dropdown into the board projects behavior; we always need that anyway and now we can install the listener more granularly.

Test Plan:
 - visted project board
 - invoked create task, cancelled dialog
 - visited project feed
 - visited project board
 - invoked create task, cancelled dialog (FAILED pre patch...!)
