test_open has too much output

[Dimitar Misev]

This is unnecessary output in the systemtest. For each case it should say something along the lines of
"Check doGet() with enabled CORS on a sub-controller… ok/failed."
All the rest here makes it hard to figure out what's the result, which test passed and which failed.
