Fix a bug where options menu was not showing.

There were two issues that stopped the options menu from
showing properly. First, the SettingsPreferenceFragment did
not call its super class, causing the Lifecycle methods to
never be called. Second, the options menu was not being
invalidated which also stopped the Lifecycle methods from
being called.
