fix problem when install bugs guzzlehttp/guzzle and satisfiable #12
Description
Problem 1
- Root composer.json requires flotfeali/payping-client * -> satisfiable by flotfeali/payping-client[0.0.1].
- flotfeali/payping-client 0.0.1 requires guzzlehttp/guzzle ^6.2 -> found guzzlehttp/guzzle[6.2.0, ..., 6.5.8] but it conflicts with your root composer.json require
(^7.2).
