Remove LocaleManager.getSafeLocale

[nbradbury]

This PR removes getSafeLocale() from LocaleManager. That code was added as a workaround for a bug in Android 7, but we no longer support that version so the function was unnecessary.

Passing CI should be sufficient to approve this.

Changes make sense to me, thanks for cleaning up. For posterity, the workaround introduction and explanation appear to be in #7413.
