[BUG-FIX] Fixed uninitialized boolean in ProfilesOperations.cpp.

While trying to help yallah with an issue with the JSON-API load profile feature (http://forum.xbmc.org/showthread.php?tid=176988), I came across uninitialized boolean which might (and actually is) break the feature.
I have no idea how it worked until now but obviously, it must be fixed.

@Montellese Please review it.

Thanks
