Better error message when no snapshotUrl configured for a MavenBndRepository

[brampouwelse]

Took me some time to figure out what bnd was trying to tell mw with the message

error: my-project: No metadata for revision my.group:my.artifact:1.0.0-SNAPSHOT

Traced it down to the MavenRepository#resolveSnapshot method ( https://github.com/bndtools/bnd/blob/ba0bd37c2c33afe4ccfd8660b1a37b1c1ac52eaa/biz.aQute.repository/src/aQute/maven/provider/MavenRepository.java#L225 )

I forgot to configure the snapshotUrl ... A more informative message at this point could have been of great help and would probably have saved me an hour (or 2).

Maybe something like

Trying to resolve snapshot revision 'my.group:my.artifact:1.0.0-SNAPSHOT' but no snapshotUrl configured.
