Fixing misnamed histograms.

In https://codereview.chromium.org/53283003 I added new histograms for
tracking double tap related statistics. However, the histogram names did
not match between histograms.xml and UMA_HISTOGRAM_ENUMERATION. This CL
changes histograms.xml to the names used in UMA_HISTOGRAM_ENUMERATION.
