Tagtree 'Play Next' Menu: Eliminate redundant filename retrieval

The file name for a track in the database has been
retrieved already, before its context menu is displayed,
or a hotkey is executed, see:
https://github.com/Rockbox/rockbox/blob/8a22d2678a9fff97fd159a4b2eb45e637f08c79f/apps/tree.c#L811

So, skip over tagtree_current_playlist_insert and instead
use playlist_insert_track() directly, when user selects
something from the "Playing Next" menu or uses a hotkey.
