Improve the charge test

[morukele]

At the moment, the test in the test/api/charge.rs file has hard-coded values. These values are directly retired from my Paystack integration. This is not an ideal solution because if someone uses their own API key, the tests will fail.

To fix this issue, you would need to figure out a way to retrieve those values from the integration so that they will not be hard coded.

If you are interested in fixing this, please indicate and take a short at it.
