This PR is fixing the following issues with record groups:
- [x] [Backend] - Only update view groups when a field is edited if this
one already has view groups
- [x] [Backend] - Editing a Select field metadata option brake view
groups
- [x] [Frontend] - Changing the group by field from one to another brake
record group and doesn't remove the previous ones
- [x] [Frontend & Backend] - Mark `kanbanFieldMetadataId` as deprecated
in favour of `viewGroups.fieldMetadataId`
Also the following has been checked:
- [x] Properly displayed a table with only one view groups
- [x] Properly displayed a table without view groups
