Move isSingleProjectMatch() to RemoteConfiguration interface

The logic used to identify whether a configuration is related to a
single project as opposed to a family of project, is the same across
destination or source targets.

Provide a default  isSingleProjectMatch method so that it can be
leveraged by both replication (for DestinationConfiguration) and by
pull-replication (for SourceConfiguration)
