Replaces hard-coded API key from Integration tests with a const
Moves EasyClient initialization to the Constants class
(to increase performance because every EasyClient initialization is a live API call because of the API key validation)
I made a test to test how many times the Constants class will be initialized and it happened only once.
The last commit is decreased the test time about 3sec (from 7-8 to 5sec)
