### Bug description

Using the custom link doesn't work for random numbers

### Steps to reproduce

1) create standard link
2) copy the randrom number 98a7sdaskjdhas
3) delete this link
4) create a new link
5) edit the link so it's that random number 98a7sdaskjdhas
6) NC will say the link is 98a7sdaskjdhas, but when you do website.com/s/98a7sdaskjdhas the link doesnt' work.

### Expected behavior

If the link is deleted, surely it should be cleared from the DB and it should be able to be used again.
This is useful if one wishes to change the folder location on the server but keep the shared link for clients
