Verification fails for test keys

[idoqo]

I keep getting an InvalidArgumentException: A Valid Paystack Secret Key must start with 'sk_'. which seems to be happening because Paystack's test keys begin with 'pk' instead.

Maybe we could update the checker code in the Paystack() constructor or find a better way to check for valid keys.

Steps to repeat: (Describe how the issue can be repeated by someone who is to work on it)

1. Generate a test key from paystack dashboard.
2. Attempt to pass test key as a parameter to the constructor.

I know this has been closed but since no reason was given for those who may stumble on this in future, here:

Paystack has public and secret test keys. The public key begins with pk_ while the secret key begins with sk_. Use the appropriate key and all will be will, be it in test mode or live.

composer dumpautoload -o

then clear Laravel config cache

It worked for me
