Do not overwrite empty DefaultBranch (#22708)

Browse Source 
Fix #21994. 
And fix #19470.

While generating new repo from a template, it does something like
"commit to git repo, re-fetch repo model from DB, and update default
branch if it's empty".


19d5b2f922/modules/repository/generate.go (L241-L253)

Unfortunately, when load repo from DB, the default branch will be set to
`setting.Repository.DefaultBranch` if it's empty:


19d5b2f922/models/repo/repo.go (L228-L233)

I believe it's a very old temporary patch but has been kept for many
years, see:
[2d2d85bb](https://github.com/go-gitea/gitea/commit/2d2d85bb#diff-1851799b06733db4df3ec74385c1e8850ee5aedee70b8b55366910d22725eea8)

I know it's a risk to delete it, may lead to potential behavioral
changes, but we cannot keep the outdated `FIXME` forever. On the other
hand, an empty `DefaultBranch` does make sense: an empty repo doesn't
have one conceptually (actually, Gitea will still set it to
`setting.Repository.DefaultBranch` to make it safer).
