Add failing test for script with arguments

This is failing bc I misunderstood `eval` in Redis

Eval is: EVAL script numkeys key key key arg arg arg

Keys here is not the NAME of the argument, as I thought, but rather an
input parameter in full

There's no named arguments in Redis. I assumed that by reading examples
from the C# API Client in the Rate Limiting implementation docs.

Args and Keys are referenced like KEYS[1] KEYS[2] KEYS [3] and ARGV[1]
ARGV[2] ARGV[3]

Let's fix that in the next few commits
