Make logging of user actions consistent with histograms for OTR.

Previously, we would not record user actions in UMA when an OTR
(Incognito) window was active. However, since user actions don't
contain any PII it was just causing a confusing discrepancy in
counts when compared to histograms. This CL makes them consistent
by making user actions be logged regardless of the OTR state.
