Fix CommandSourceStack#bypassSelectorPermissions (#10837)

The previous implementation would throw a command exception if the
CommandSourceStack had its bypassSelectorPermissions flag set to true,
which is the incorrect behaviour.

Instead, it should only throw an exception if the flag is set to false
and all its other checks "fail" too.
