status: don't suggest "git rm" or "git add" if not appropriate

The display of the advice '(use git add/rm [...])' (when there are
unmerged files) after running 'git status' is now depending of the
mark, whether it's 'both deleted', 'deleted by us/them' or others. For
instance, when there is just one file that's marked as 'both deleted',
'git status' shows '(use git rm [...])' and if there are two files,
one as 'both deleted' and the other as 'added by them', the advice is
'(use git add/rm [...])'.

The previous tests in t7512-status-help.sh are updated.

Test about the case of only 'both deleted' is added in
t7060-wtstatus.sh
