[5.x] Improves "where" modifier value check

[JohnathonKoster]

This PR closes #10679 by only applying the default == operator if the number of supplied parameters is less than 3.

Looks like a if the value is passed in as a string instead, it still breaks.

Should these two work in the exact same way, as we aren't strict checking?
where('product_count', '!=', '0')
where('product_count', '!=', 0)

Good catch. I've refactored the approach to only apply the default condition if the supplied number of params is less than 3
