Phalcon1: Fixed getting fields

[sergeyklay]

In some cases Phalcon's model message has more than one field.
For example:

    public function validation()
    {
        $this->validate(new Uniqueness(
            [
                'field' => ['phone', 'email'],
                'message' => 'User already exists!'
            ]
        ));

        if ($this->validationHasFailed() == true) {
            return false;
        }

        return true;
    }

In this case $message->getField() returns:

Array
(
    [0] => phone
    [1] => email
)

Merge the latest changes from 2.0 and the build will pass.
