Current MultiTL is statefull and keeps track of what loader is used to load what template rather then going every time strictly in order of all TLs it knows of. Hence to enable true overriding of templates we need to make sure it is reset when new template is added to the workspace or when one is deleted.

Work around is to touch fmTemplateLoaders configuration to bump MultiTL or restart in case one needs to override template previously served by other loader.
