api: fix multiple bugs with statuses endpoints (#7785)

* fix commit statuses api url

* search refs before passing sha

* adjust tests

* directly search tags and branches names + remove un-needed check in NewCommitStatus

* fix comment

* de-duplicate code

* test: use relative setting.AppURL

* Update routers/api/v1/repo/status.go
