Conditional rules don't explode

[bytestream]

Conditional rules don't explode correctly on this line: https://github.com/proengsoft/laravel-jsvalidation/blob/master/src/Javascript/RuleParser.php#L96

Wrapping $rules in an array [ $rules ] results in a multi-dimensional array, and subsequently explodeRules() doesn't handle it correctly.

Replacing with (array) $rules seems to fix the problem. Thoughts?
