Add back in log info about histogram hashes
Add back in log info about histogram hashes

This was seemingly inadvertently deleted in a CL

http://src.chromium.org/viewvc/chrome?view=rev&revision=16023

The change should have no semantic impact on the running of the program
(unless the user enables logging), and it helps me isolate actual names
of histograms for unknown hashes that appear on the histogram dashboard.
