When using the filter controls in the list view on a relationship field,
the select options would clear after clicking outside of the component
then never repopulate. This caused the component to remain in an
unusable state, where no options would appear unless the filter is
completely removed and re-added. The reason for this is that the
`react-select` component fires an `onInputChange` event on blur, and the
handler that is subscribed to this event was unknowingly clearing the
options.
This PR also renames the various filter components, i.e.
`RelationshipField` -> `RelationshipFilter`. This improves semantics and
dedupes their names from the actual field components.
