Tags still visible in transactions after deletion

[marviins87]

Bug description
I am running Firefly III version 4.8.0.3, and my problem is that tags are not detached from my transactions after deleting tags.

Steps to reproduce

1. Create a tag (id 45, name testtest)
2. Edit a transaction and add testtest tag
3. check the tag (/tags/show/45) and open the corresponding transaction (transactions/show/12374)
4. Delete tag testtest (/tags/delete/45) ("Gelukt! Tag "testtest" verwijderd")
5. open transaction 12374 again (/transactions/show/12374)
6. Tag testtest is still attached to it and visible in the transaction.
7. check the tag (/tags/show/45), doesnt exists so redirect to tags page (/tags)

expected behavior
The tag shouldn't be visible in the transaction after deleting it.

Extra info

• In the DB the deleted_at column contains a timestamp so it's deleted in the DB.
• When i manually set the field back to NULL the tag is back and all transactions are visible like they should.

Nice find. This will be fixed in the next release.
