registry: when removing a cached-but-no-longer-existing plugin, only remove features that belong to it

Browse source 
When a plugin file no longer exists, e.g. because it's been removed or
renamed, don't remove all features in the registry based on the *name*
of the plugin they belong to, but only remove those who actually belong
to that particular plugin (object/pointer).

This fixes issues of plugin features disappearing when a plugin .so file
is renamed.
