Cperello/captiveportal fixes

Captive portal suite fixed. However, I expect some breakages, I'm not sure the suite is testing everything, for instance, I found that Quota event watches was in the wrong path and the failure was not detected by the tests, I just found it while debugging other issues, but that's for the post freeze bug fixing...
