Thomas Gummerer 8e4c8af058 push: disallow --all and refspecs when remote.<name>.mirror is set
Pushes with --all, or refspecs are disallowed when --mirror is given
to 'git push', or when 'remote.<name>.mirror' is set in the config of
the repository, because they can have surprising
effects. 800a4ab399 ("push: check for errors earlier", 2018-05-16)
refactored this code to do that check earlier, so we can explicitly
check for the presence of flags, instead of their sideeffects.

However when 'remote.<name>.mirror' is set in the config, the
TRANSPORT_PUSH_MIRROR flag would only be set after we calling
'do_push()', so the checks would miss it entirely.

This leads to surprises for users [*1*].

Fix this by making sure we set the flag (if appropriate) before
checking for compatibility of the various options.
