Before this rev., it crashed when the user used the quick create
to create several records (very quickly, or on a slow network),
e.g. on crm.lead (there must be a date field on the kanban record
to reproduce the crash).
The crash occurred when the 'read' RPCs for the created records
return misordered. For instance:
1) 'name_create' record 1 (called and returned)
2) call 'read' for record 1
3) 'name_create' record 2 (called and returned)
4) call 'read' for record 2
5) 'read' for record 2 returns
6) 'read' for record 1 returns
At step 5, the kanban column was updated with the new state, but
this state already contained record 1, which wasn't fetched yet.
This rev. ensures that the created records are added to the state
once they are fetched and ready to be displayed, not before.
