A change between v1 and v2 of docker-compose meant that
container names moves from using _s to -s for their parts.

mwcli depends on this name riht now and thus breaks with v2.
This change removes the dep on names, instead selecting containers
based on labels which remain the same between docker-compose version.

Thanks for @migr for spotting the issue.

Also continuation of 1a1e09ad

Now rather than only moving forward, the update command
would be able to switch to previous version in case folks
want an easy path to rollback to a previous release.

This also makes testing some of this logic and code
a little easier :)

This follows !102.

This would give errors / warnings such as
Error: No such volume:
And these were left over from bad copy pasta

This alters the location of the sqlite db files.
It also sets a umod ALWAYS in install.php and also via
LocalSettings.php which means we should have far less
permission issues when juggling differnet things in different
contexts.

It might make snense to set umods more too, for things such as
running composer update as the wrong user etc..
