[KARAF-4116] Feature Installation - no Refresh of Fragment-Host bundle upon installation of fragment bundle

From KARAF-4116:

There is a regression in feature installation behavior whereas later installation of a feature which contains a fragment bundle and references a feature providing the fragment-host bundle the fragment-host is not refreshed after feature install, causing the fragment to remain in state "INSTALLED".

Manual "refresh" of host-fragment bundle will resolve the relationship and put fragnent into "RESOLVED" state with host:<host-fragment bundle-id>
