commands.push: use paths API

ui.path instances now collect most of the data used by commands.push().
Move away from ui.expandpath() and call ui.paths.getpath() to get a
path instance.

Some "pushing to" output was dropped as one test demonstrates. I believe
the dropped message was redundant with the error message and the change
to be acceptable.
