transport-helper.c::push_refs(): ignore helper-reported status if ref is not to be pushed

If the status of a ref is REF_STATUS_NONE, the remote helper will not
be told to push the ref (via a 'push' command).

However, the remote helper may still act on these refs.

If the helper does act on the ref, and prints a status for it, ignore
the report (ie. don't overwrite the status of the ref with it, nor the
message in the remote_status member) if the reported status is 'no
match'.

This allows the user to be alerted to more "interesting" ref statuses,
like REF_STATUS_NONFASTFORWARD.
