pull: Ensure console state for multiple GPG verification messages

If there are multiple signatures to verify, we would attempt to
display them multiple times, but we can only call
`gs_console_end_status_line()` if the console has been enabled.

Ensure we turn back on the console after printing our status.  This
will result in extra newlines, but fixing that cleanly would require a
saner GSConsole API.
