remove automounter from the status thread

it's now in shellchat. In general, the program that is assigned
as the initial app context is responsible for ensuring the
PDDB is mounted. Thus, if `vault` were to become a stand-alone app,
it should include some code to make sure the PDDB is mounted as
part of its boot sequence.

The reason is that it allows the initial app to guide the
power-on experience, instead of delegating this to the `status`
bar, which is oblivious to the state of the app.
