New tests for AppView and PickListVIew

* Initialization of AppView calls a method
* That method creates a query from a random numerical seed, and
* Fires an ajax call to get a list of fingerprint values
* Randomly samples one of these and triggers an event,
* PickListView listens for bootstrapping event

New AppView functionality is not yet well isolated and thus
is under-tested.
