The GetMessages observation could potentially include a pseudo-deleted #227
Description
The GetMessages observation could potentially include a pseudo-deleted
message which is either:
- a message that is inflight
- a message that has already been executed
- a message that was not included in the observation due to size limits
In all cases, since we don't need to execute these messages, we don't
need to fetch their sender's nonce.
