Do not attempt to show detailed tooltips without torrent metadata. Closes #6768.

Browse Source 
Computations for detailed tooltips are not protected against unavailable
metadata, that leads to asserts or crashes. But since those tooltips are
useless in this case, do not show them at all. Inform user that detailed
tooltip becomes available once torrent metadata are fetched.
