Fix renaming files to be installed that are matched by a wildcard.

The problem is that files matched by an "install" rule are currently not
added to the target artifacts if a build graph already exists and they
are "implicitly added" by adding or renaming a file in a group matched
by a wildcard (i.e. the change happens without touching the project
file).
