remove default value and type hinting for magic methods

[smokills]

I was writing some tests, and in creating a mock of this class I came across this error:

ErrorException: Declaration of Mockery_1_Appstract_LushHttp_Lush::__call($method, array $args) should be compatible with Appstract\LushHttp\Lush::__call($method, array $arguments = Array)

Looking at the signature of the __call methods, I noticed that default values had been entered.

Since this methods are always handled by php itself, and $arguments will always be an array, even if no arguments were passed to the called methods, to avoid mocking problems I've removed defaults and tipe hinting declarations.
