DataTransformer not called on filter fields

[shylux]

I will start this with a disclaimer that we have some customization on top of you bundle so it might not be a SyliusGridBundle error, but i think it is.

I used the DateFilter which gave me incorrect results. Upon inspection i saw that the Query used my localized date format. This localized date format should have been transformed by the default symfony date field type (i customized the filtertype to use that field).
Using some dump statements i discovered that the filter type data transformer is called after the the filter is applied. So the filter is using raw query data.

With some more digging i saw that your implementation does register a view transformer -> (transformer). But you do the same thing in the filter.

Can you look into it? Thanks 👍
