completion: fix completing args of aliased "push", "fetch", etc.

felipec · gitster · commit 880111c11bef · 2014-04-09T14:22:18.000-07:00
Some commands need the first word to determine the actual action that is
being executed, however, the command is wrong when we use an alias, for
example 'alias.p=push', if we try to complete 'git p origin ', the
result would be wrong because __git_complete_remote_or_refspec() doesn't
know where it came from.

So let's override words[1], so the alias 'p' is override by the actual
command, 'push'.
