fix: id generation algorithm for complex filters

[inkedsquid]

What does this PR do ?

The filter ID generation algorithm is potentially flawed, complex filters like

{
        "and" : [ 
          { "equals": { "city": "Montpellier" } }, 
          { "equals": { "city": "Nimes"} } 
        ]
}

and

{
        "and" : [ 
          { "equals": { "city": "Montpellier"} }, 
          { "equals": { "city": "Lyon"} } 
        ]
}

will inherently get the same ID although they are different.

This PR isn't done and only represent the current issue Koncorde filters ID have.
