bugfix/InvalidParamTypeProvidedNULL: fixed param apiKey = null in login() method

[eneiasramos]

Description (*)

I got an error using API when applying the last commits to my master branch.

Apparently any API call is generating the error: Invalid param type provided ("null")

Applying the fix the error disappears.

I have this commit 41ea3c6 in production, which uses JSON-RPC with basic auth with requests daily, so far nothing bad is reported.

Another consideration to do is that apiKey parameter can be null ( apiKey = null ).
However the invalid_request_param fault is triggered in this case.

if (empty($username) || empty($apiKey)) {
            $this->_fault('invalid_request_param');
            return;
        }

So it doesn't make sense that apiKey could be null at this point :)

We should not change methods parameters. Default null does not do anything. Removing it should not change you problem.
