One call to sendUsageData wasn't dependant on usage log setting

The usage data wasn't being queued, but sendUsageData was getting called anyway.

In any case, the little yellow triangles seem to me to be a fairly core feature of XPrivacy, and an essential part of a restrict, test, refine cycle. I don't quite see why it should be an expert setting.

Of course, if we do end up designing a better test cycle ui, XPrivacy could always enable it just for that app during the testing phase.
