Opening bug to backport to 3.6.2+

+++ This bug was initially created as a clone of Bug #345640 +++

If a composite bundle exports and imports the same package things do not work as expected when the resolver chooses the composite to be the exporter of the package.  When ends up happening is we incorrectly create a surrogate that has metadata to export and import the package.  The resolver for the surrogate/composite framework then may choose to make the surrogate an importer or an exporter of the package.  Since the surrogate is at bundle id 0 it is very likely that it will be resolved first and given preference to be the exporter.

So now we have the composite bundle on the outside thinking it is the exporter of the package, and the surrogate on the inside thinking it is the exporter of the package, but meanwhile no one gets wired to the actual provider of the package, which must be from another bundle installed inside of the composite.
