Samael Wang c4ecad6c4b Bug 1364364 - Part 5.2: Remove browser.sessionhistory.cache_subframes and fix test cases relying on it. r=smaug
browser.sessionhistory.cache_subframes has been disabled for 12yrs. It's not
actually maintained and it leaks content viewers. Using this unreliable feature
in test cases is a bad practice, so remove the pref completely and fix existing
test cases.
