Bug: GrantTypeInterface not respected

[tobias-trozowski]

when enabling a grant type via enableGrantType the provided type GrantTypeInterface is not respected ($grantType->revokeRefreshTokens($this->revokeRefreshTokens);).
A non-existent method will be called.

I just added unit test to test against a custom grant type

I think this is related to the changes in PR #1189. If I am understanding correctly, an update to the interface to add the revokeRefreshTokens method in the next major release should fix this. Can you confirm this is what you are expecting @tobias-trozowski?

It threw me a little that your PR isn't addressing this specific issue (but thank you all the same for submitting this).

@Sephster i wouldn't say "expect" but adding the method would do just fine. Thank you so much!

Thanks @tobias-trozowski - the interface change will be added to the next major release. Thank you for the PR too
