fix(logger): ignore session logging during setup

[ArtificialOwl]

This fix a regression from #47105 that lock installation process on 29.0.5 (but no 30 😕 ) when using the web interface

[nickvergessen]

Or we wrap the code with an isInstalled() check?

[ArtificialOwl]

if we can ignore slow session logging during installation process, I could check this in base.php and send a null logger to the Session

[nickvergessen]

I think both makes sense.

@nickvergessen please check this new way of fixing the issue.

[ArtificialOwl]

Thanks. Fixed, squashed and rebased

(no idea if an urgent new release of 29 is needed)

Confirmed that this fixes nextcloud/docker#2283

This breaks web based installations. While occ maintenance:install is a workaround, this is a serious bug. There are reports on the community forum as well. I think we need to do a new release.
