fix: Allow to delete repos with invalid urls (#20921)

Fixes #20921

Normalization of repo url is attempted during repo deletion before comparison with existing repos. Before this change, it'd fail on invalid urls and return "", resulting in permission denied. This ended up in a state where people can add repos with invalid urls but couldn't delete them. Return raw repo url if url parsing failed. Add a test to validate the deletion can be performed and make sure it fails without the main change.

This needs to be cherry-picked to v2.11-2.13
