Payload doesn't have elapsed field.

Hi, I'm attempting to use the robotframework-Testrail-reporter from here: https://github.com/vincenzo-gasparo/robotframework-testrail-reporter

And found out that the actual pip version 0.3.14 has an issue with setting the payload to send to testrail here: https://github.com/travispavek/testrail-python/blob/9a16b957040dcc38d2f28b03ea41efa4946e26b6/testrail/api.py#L603

The payload has not been initialized with an 'elapsed' so I get and index out of range. Once removed I'm able to send to testrail my robot reports. Thank you for correcting issue. A new release would be welcomed. -Ric
