Fix issues with card keys

[dodu94]

Description

There is a need in F4Enix to clean card keys like *TR1 -> TR1 or F6:n -> F6. The pattern that was implemented to clean this though had effects also on other cards such as WWE:N -> WWE. This can create a problem since in the same input one can have WWE:N and WWE:P, meaning that only one card would be retained in the input. This behaviour has been corrected.

Fixes #112
