Upgrade to 1.21 Broke Repo - Branches Missing

[NotGovernor]

Description

I have a server on docker compose pinned and updated daily to gitea:latest

The recent upgrade to version 1.21 has broken sever repo's in the following way:

1. There are several branches in this repo, but it's only showing a count of 1 (the feature branch I pushed before realizing there was an issue with the server).
2. Clicking on Branch on the bar takes you to a 500 error (because it seems to be looking for the master branch it has lost)

An error occurred:

LoadBranches, branch does not exist [repo_id: 3 name: master]

So it appears to have forgotten all the branches, even though the home page for the repo shows the master branch.

Pushing anything to the lost branches seems to restore them. Pushing something new to the master branch has resolved the branches list page error -- though the forgotten branches are tragically still missing. Anything people didn't have locally seems to be unreachable.

Quite the jump scare for the team today. :D
