[TYPO3-core] FYI48 #16751: Bug: Uninitialized variable triggers exception in Update wizard

[François Suter]

FYI: the attached patch will be committed to trunk when commit lock is 
released

Type: Bugfix

Bugtracker references:
http://bugs.typo3.org/view.php?id=16751

Branches:
Trunk

Problem:
An uninitialized variable triggers an exception in the Update wizard, 
breaking the update process.

Solution:
Initialize that variable to make sure it's an array. I consider that a 
no-brainer.

Cheers
