When __git_func_wrap was fixed to set correctly __git_cmd_idx in
cea232194d (completion: bash: fix late declaration of __git_cmd_idx,
2021-06-18) no test was added, therefore we could hit the same bug in
the future.
To ensure that doesn't happen add a test which adds an alias for 'git
add' with __git_complete, and then pretend the user typed this alias.
To make sure __git_cmd_idx is correct we add the --update option to
ensure the result of __git_find_on_cmdline (which uses __git_cmd_idx) is
correct. When __git_cmd_idx isn't correct __git_find_on_cmdline fails,
and therefore the --update option isn't interpreted correctly.
