Update test implementation (test/histograms.h) to be more similar a real implementation (where histogram get functions return a Histogram pointer). Add check that the name of a histogram does not change. BUG=webrtc:5283 Review URL: https://codereview.webrtc.org/1528403003 Cr-Commit-Position: refs/heads/master@{#11161}
