Subject: Fix http authentication to a different realm on the same server

This is a regression caused by the NTLMv2 authentication patch.
I have manually tested NTLMv2 authentication against MS IIS and reverting
these two lines does not break it.

Task-number: QT-5209
Change-Id: I64159cbe468e1a7f834f8726fd0c9d4ab4c54b38
