Subsystem core tries to shutdown the framework when it has a framework dependency like org.osgi.util.tracker

When performing a shutdown of the subsystem core bundle it tries to stop the framework because there is a org.osgi.util.tracker import package.

Also in the same situation described above when trying to shutdown the framework by calling stop on bundle 0 it can fail with:
[org.apache.aries.subsystem.core.internal.StopAction] : An error occurred while stopping resource osgi.identity; osgi.identity="org.eclipse.osgi"; type="osgi.bundle"; version:Version="3.10.0.v20140606-1445"; singleton:="true" of subsystem org.apache.aries.subsystem.core.internal.BasicSubsystem@25760667
