Parameter -c changes all-xccdf.xml

[MajoDurco]

Main problem is that if PA run with --contents parameter which takes path to all-xccdf.xml, then this file is changed even though it should not be. When you run PA for a second time it throws the traceback.

BTW, this was reported in august downstream as rhbz#1368823.

I suspect this line

preupgrade-assistant/preupg/application.py

Line 458 in f087c8d

XccdfHelper.update_platform(self.content)

qa_ack: downstream suite needs to work around this, so removing it would be nice, and would actually constitute the verification test itself.

Solved #281.
