Tags persist if table was deleted and recreated with same name

[jh-RLI]

Description of the issue

This could also be a feature: If a user deletes the table and then recreates it under the same name, all tags are still available.

Steps to Reproduce

1. Create table "test_pers_tags"
2. Navigate to table detail page
3. Add a tag
4. Delete table
5. Create table "test_pers_tags"
6. Navigate to table detail page and view tags

Ideas of solution

If we want to change this, we should also delte the table - tag relation.
