Fixes 6971, fix test failure in Login_spec.js (test for formless login failed because test tried to login w/ superuser which is not allowed. Not sure why it only happened now.). Create new user in UITestFixture for this test.

Fixes #6919, do not check for host in regex group in log importer if format has no regex. Also add nginx json log to log importer system test.

unset a possible set idSite in the logout url, this should fix the error message not having access for idSite after logout.

fixed some system tests. the order change of some device reports changed as they have sometimes same orderid and as we moved some ecommerce reports it results in a different order now
