Fix tag search

[Pytal]

Fix #3662 and make minor updates to vue-select prop handling

The limit prop is now used instead of optionsFilter to limit the available tags

Previously only 5 tags were being passed as options to VueSelect, since VueSelect handles searching internally any tag after the 5th one could not be searched for

Works.
But I have to admit, I find it weird to see only 5 tags in the dropdown and then new tags showing up when I filter. But that's a different story, I guess.

It's a browser performance thing :)
Otherwise when you have thousands of tags (automated tagging from AI and things) they slow down the page loading
