mon/MgrMonitor: only induce mgr epoch shortly after mkfs

For early clusters, if there isn't an active manager, we eventually want
to trigger a health warning by rolling over the mgrmap epoch.  We don't
want to do that if we have no active/available manager after that.  Fix
by checking ever_had_active_mgr here.
