Avoid storing Sends twice in memory and postgres checkpointers
...
- Sends are stored through put_writes, so we don't need to also store them inside checkpoint object
- On reading checkpoint, reconstruct pending_sends from the stored writes

Fix semantics of put_writes/list ( #1436 )
...
* Fix semantics of put_writes/list
- put_writes(error) should not prevent saving future successful if task is retried successfully
- put_writes(writes) should be a no-op if non-error writes already exist for that task (this prevents tasks executed more than once from modifying writes previously saved / acted on)
- checkpoints should not include channel default values (ie those without a version)
- list() should fetch and return writes for each checkpoint
* Lint
* Rm print
* Fix import

checkpoint-*: In put_writes clear any previously saved writes for this task_id
...
- Previously implementations were clearing only tasks if the index matched a previously saved one, which isn't enough to guarantee idempotency
