Fix bug #7176: Clicking TOC doesn't bring up outline

Previously LFUN_INSET_SETTINGS was misused to show the outliner. As a TOC doesn't have settings, it was no longer showed after a refactorization of LFUN_INSET_SETTINGS/LFUN_MOUSE_RELEASE because InsetToc::hasSettings() returns false.

As this is a special case, we should handle this special case in InsetTOC itself.
