Bug in the Email validator

For example, there are validation rules for the email field: ```'email' => 'required|string|email|unique:emails,email'```

This way causes that only the message of the 'email' rule to be always shown whatever rule is triggered.

But if I change the validator name other than 'email' - the problem goes away, e.g.:
```'other' => 'required|string|email|unique:emails,email' ```
