Bug fixes in the printer dialog activity and fused printer loader.

1. Fused printers loader was not using the discovered printers to update the
    historical ones. Now if a historical printer is discovered we update its state
    with the discovered, i.e. most recent, information.

2. Fixed a bug in the destination adapter of the print job config dialog that
    was leading to a crash if all printers item is selected when there are no
    discovered printers.

3.  Updated the add printers asset in the all printers screen.

4. Historical printers were not persisted by the print dialog activity.

5. Reduced the number of printers we send per transation to avoid the binder
   transaction size limit. Added sending of printers in chunks in a place
   this was missing.
