As Alexander pointed me, we should drop a tag after `git fetch`. My bad
(again). Updated on master, 2.5, 2.4 and 1.10 as follows:

    gitlab-ci: fix tag removal for a branch push job
    
    We should remove a tag after fetching of a remote repository.
    
    It is hotfix of commit 0f564f3497e6a8afd42da2175104118ba5213593
    ('gitlab-ci: remove tag from pushed branch commit').
    
    Follows up #3745
