Fix incorrect default browser summary.

- move the logic to retrieve browser candidates with unique package name
from default browser picker to the controller, so that both uses the
same logic to get the candidate list. When there is only 1 package that
can handle the web but it has multiple resolved activities, it should
be considered as the only app, and hence be set as default.
