[GITEA] Remove redundant syncBranchToDB

- The transaction in combination with Git push was causing deadlocks if
you had the `push_update` queue set to `immediate`. This was the root
cause of slow integration tests in CI.
- Remove the sync branch code as this is already being done in the Git
post-receive hook.
- Add tests to proof the branch models are in sync even with this code
removed.
