Defining a form_option "type" on StringFilter is not working

[laurentdabbb]

Hi,

On a string filter if I define a "form_options.type", this type is ignored and the default value "contains" is used.

In Sylius\Bundle\GridBundle\Form\Type\Filter\StringFilterType class, the field "type" is added only if $options['type'] is not set.
You should add an HiddenType field "type" with the value defined in "form_options.type".

Currently, if we define a "form_options.type", all the requests are executed with a "LIKE '%%'".

Thx.
