Prefer printers that have been used physically close to the current
location of the user.

Commonly the users prints on a printer that this near the user current
location. Hence if possible we want to show the user printers that he
used before and that are close to him.

Hence store the location of the previous uses of a printer and prefer
printer that are close to the user.

Unfortunately getLastLocation might not report a usable location and it
will take at least 5 seconds until the first usable location arrives. At
this time the user might have already opened the destionation spinner.
It would be unexpected for the printers to suddenly change under the
users finger. Hence it might be that we did first show the printer
without any location information and then once the location is known we
cannot update thedestination spinner anymore.

The select printer activity does not have this issue, hence in the worst
case the user has to enter this activity to select a printer and by then
the location is usually determined.

This is not ideal but better than before.
