1293 remove barcode

Fixes #1293

Link to dodal PR (if required): N/A
(remember to update setup.cfg with the dodal commit tag if you need it for tests to pass!)

To test:

1. All tests should pass
2. DataCollectionGroup info should be stored in ispyb as normal

[rtuck99]

I didn't add the create_group method as described, as it didn't really seem to add anything. After removal of the barcode and subsequent removal of all population of DataCollectionGroupInfo during updates, there is no "worrying about groups" after activity_start, you just let ispyb_store populate your ispyb_ids and then forget about it.

The only possible benefit might be some separation in ispyb_store.begin_or_update_deposition() but at the expense of managing the ispyb connection across the separate calls during begin_deposition().

Great, this cleans things up quite a lot, thanks!
