[TYPO3-core] RFC #17320: Not installing extensions in Upgrade Wizard should also get rid of the wizard

This could probably be used in the workspace migration wizard too, but 
it's a bit more touchy, because the wizard should really be run through 
when there's at least one bit of versioning/workspace-related stuff 
install. OTOH if nothing is installed and the user doesn't want to 
install anything, it should "disappear" like the other wizards do now. 
But this doesn't need to be fixed, as at least the workspace migration 
wizard does not "fail" when skipped.

Anyway this new mechanism introduces interesting possibilities for the 
wizards and we should probably revisit them all in 4.6 (for example, the 
compatibility wizard; it should be possible to make it go away too, when 
one doesn't want to switch compatibility version anymore). In an ideal 
world the Update Wizard should be completely empty in a fully updated 
installation.

> Committed to trunk, rev. 10318, so that it can be tested in RC3.

My post-commit +1 by reading and testing.

Thanks for coming up with this solution.
