i completely removed the Enum from SwaggerRedirect here which is a retired service for the /2.0 base

• all paths for this base route is not in use, so checking for the enum here does not help users.
• i think this is a better approach then adding the routeEnum param to retiredService.

This one is pretty fun bug.
I'm not sure why it is allowed, but we had 2 routes conflicting until now in WeblateEntities and WeblateUserStatistic
Both services have a base route of weblate and a enum for the first param.
The enum's have collision for the languages value.

The main problem we are going to have solving this, is backwards compatibility. My guess is that one overides the other so i could make change the base for the one that was overriden then use a redirect for all enum values other then the one that was not in use....

oh, it's not a conflict, one has a user param later and the other doesnt.
