- Forward `autocompleter` prop from `CompareFilter` to `Search`.
Allow, to use the `custom` type of search,
previously it was complaining about lack of `autocompleter`,
even though it was provided.
- Move `path` in Storybooks example to a parameter, to allow setting it in unit tests.
- Add few tests for FilterPicker.
- it renders the basic storybook example without throwing an error
- it forwards `autocompleter` & `type` props
