[TYPO3-core] jump URL "transfer session" regression

[Ernesto Baschny [cron IT]]

Hi,

this regression was introduced by the jumpUrl fix:

http://forge.typo3.org/issues/46463

I would be glad if you would be so kind to take a look at it, and maybe
even review the proposed patch and/or test it, especially the Security Team.

Thanks!

Regards,
Ernesto
