Remove the permuted entropy cache from prefs

The (Caching)PermutedEntropyProvider was removed in m73, commit
c4267fbbca666a8a354f01bf905adfdc0d917f1a. Since then, the provider's
cache has been cleared from prefs on metrics initialization. It should
be cleared from most installs now, so stop clearing it, and remove the
pref.
