[TYPO3-core] RFC #17182: migrateWorkspaces in Install-Tool shows up even if nothing has to be done

[Tolleiv.Nietsch]

This is an SVN patch request.

Type: Bugfix

Bugtracker references:
http://bugs.typo3.org/view.php?id=17182

Branches:
trunk

Problem:
After #17102 the wizards shows up nearly every time even if the wizard 
would not process/update anything afterwrds.

Solution:
The attached patch checks if the old style admin field is used or if 
there are any workspaces which use stages without having 
sys_workspace_stage records assigned - this way the wizard won't show up 
if it ran once.

Cheers,
Tolleiv
