Matching tuples using wildcards and a "where" clause triggers empty_enum_arguments

[fellipecaetano]

The following snippet is interpreted as a violation of the empty_enum_arguments rule:

switch (email, password) {
    case (_, _) where !email.value.isBlank && !password.value.isBlank:
        return .valid(email: .idle, password: .idle)
    default:
        break
}

I was expecting a violation of a different rule, or rather that no rules were violated at all.
