Fix configuration of aliased plugins

Normally Maven tries to look up plugin configuration using plugin
coordinates taken from plugin descriptor.  This works with pure Maven
as plugin descriptor always matches <plugin> reference in POM.
However in XMvn they can differ when plugin artifact is resolved
throug artifact alias, so XMvn should force use of coordinates
specified in <plugin> in POM.
