Do not delete tags without notes

Hi :slight_smile:

I have slowness problems and my first sync takes a long time.
@laurent told me that the slowness surely comes from the large number of tags I have (3729 Tags and 30045 NoteTag):

So I started deleting a few tags (around ten :sweat_smile:) then I came across this topic which says that tags are never deleted from the database.

So I ask myself: is there any point in deleting tags? (from a performance point of view, compared to the performance issue mentioned by @laurent)
