TypeError when using `eval()`

[timobleeker]

Hello!

I can see that the eval implementation of mock_redis does not do anything:

mock_redis/lib/mock_redis/database.rb

Line 281 in f4a151d

def eval(*args); end

But I do get a (for me) surprising error when running my tests on a piece of code that uses eval

Rspec fails with a TypeError:

     TypeError:
       wrong argument type Hash (expected binding)

Is this an issue in mock_redis, or in my understanding? 😄

The README mentions in the Unsupported Commands section that eval isn't supported. The error here is odd, but at the end of the day we don't support eval.

Would welcome a PR with any improvement.
