Work on issue #17624121: Settings crash while launching on wiped device

Cleaner paths and better error reporting when a problem goes wrong
while binding an application.  This gets rid of the (recently added)
error about removing a process that hasn't been killed, and cleanly
kills the process along with more detailed errors about where things
failed.
