* Makes the ModeratorsQuery not return an exception on invalid role
The current implementation of the query would yield an exception when
recieving an invalid state parameter. As per the [GH issue
discussion](https://github.com/forem/forem/issues/10060#issuecomment-692295217),
Zhao recommended to change its behaviour and not trigger an exception in
this condition.
This commit does just that. If the state argument is invalid, the query
now returns an empty result set.
