env variables returning null if config is cached

[jeygith]

Hi! good work on this however, there's a slight issue with how you get the env variables in the Mpesa class. Once the config is cached, via config:cache, the .env file is no longer loaded and calls to the env function return null. I'd suggest you create a config file for the sdk where the consumer keys and secret or any other variable can be set.

These can be fixed on the move, you dont need to wait for a whole release to correct such. Are pull requests ok?

[mossey]

Yeah @nikklass PRs are okay
