Created some tests to protect some basic bluetooth
pairing dialogs features from regressing. Most of the
tests in this CL ensure that the view is properly
created and that it is properly updating the
associated controller when a relevant action occurs.

Dialogs displayed when attempting to connect
to a bluetooth device have been refactored so
that they use a proper dialog fragment. Hardware
dependencies have also been refactored into a
controller class to make it possible to test
these dialogs as well as the controller
independently of one another.
