AdministrationRole's templates input value doesn't handle multi-word names

[diimpp]

This is the issue, that I've initially described at https://github.com/Sylius/RbacPlugin/issues/64 but problem is separate one.

https://github.com/Sylius/RbacPlugin/blob/master/src/Resources/views/AdministrationRole/update.html.twig#L18

Change is around value property.

--- <input type="text" id="sylius_rbac_administration_role_name" name="administration_role_name" required="required" value={{ administration_role.name }} >
+++ <input type="text" id="sylius_rbac_administration_role_name" name="administration_role_name" required="required" value="{{ administration_role.name }}" >
