mq: simplifies the refresh hint in checklocalchanges

The `checklocalchanges` function in the `mq.queue` class takes a `refresh` argument that
changes the error message of raised exception. When refresh is
`True` the exception message is "local changes found, refresh first" otherwise,
the message is just "local changes found".

This changeset is the first of a series that extract `strip` into a standalone
extension (as discussed in issue3824). This `checklocalchanges` function is
indirectly used by the strip command. But in a standalone strip extension the
concept of "refresh first" has no sense. In practice, When used in the context
of the strip commands `refresh`'s value is always `False`.

So my final goal is a be able to extract the `checklocalchanges` logic in a
standalone extension but to keep the part related to "refresh first" in the mq
extension. However the refresh handling is deeply entangled into the
`checklocalchanges` code. It is handled as low a possible at the point we raise
the exception.

So we moves handling of refresh upper in the `checklocalchanges` code. This will
allow the extraction of a simple version in the strip extension while mq can
still inject its logic when needed.

Two helper functions `localchangesfound` and `localchangedsubreposfound` died in
the process they are replaced by simple raise lines.
