Description

When pushing a non-default branch (e.g. everything except master) to an empty repository, the dropdown menu for branch selection is wrongly labeled master. The dropdown menu shows the correct branches.

On further investigation I noticed that the link to the commits for the current branches links to https://try.gitea.io/foobar42/test-repository/commits/branch/master which produces a 404 error.

Also visiting the branches overview (https://try.gitea.io/foobar42/test-repository/branches/) lists master as default branch (which does not exist) but does not list the develop branch.

In general it seems like the UI gets confused when there is only one branch which at the same time is not the default branch.
