This PR is part 3 of RecordPicker refactoring.
It aims to remove all effects from:
- (low level layer) SingleRecordPicker, MultipleRecordPicker
- (higher level layer) RelationPicker, RelationToOneInput,
RelationFromManyInput, ActivityTargetInput...
In this PR, I'm re-grouping Effects in ActivityTarget section and
creating a hook that will be called on inlineCellOpen
