GET request error

[rickeyf]

In example for time tracking of issue we refer to the next request
GET /api/issues/{issueID}/timeTracking?{fields}

For GET request we need send params in 'query' key for Guzzle Http, but in function buildOptions we can see that it is impossible to do.

In result we got wrong request

The solution is to change the $defaultOptions parameter
$defaultOptions = [ 'headers' => $this->buildHeaders() ];
and add additional action for value $options
