narrow: update the narrowspecs to new ones after pulling when widening

The ellipsis case updates the new narrowspecs at bundle2 handling code, and
non-ellipsis widening didn't use to work and never set the new narrowpats.
Previous pacth added server side logic for widening without ellipsis. This patch
adds the missing repo.setnarrowpats() so that we set the new narrowpats after
widening in non-ellipsis cases also.

This makes widening with non-ellipsis case work but there are certain things
which we can improve.
