[Storybook] Grid with filter: the filter doesn't work properly

[siffash]

Steps to reproduce:

1. Click on User ID filter icon and put 41512
2. Click on Name filter icon and put Brad
3. The result is "We couldn't find any items", all is good...
4. Click on Name filter icon and clear the input field
5. You'll see all the records again. Note that the User ID filter is still active, and if you click there you'll still see 41512 which we put there before, but it's not taken into consideration anymore.
