[Bug]: Cloud test runner reports "Could not find error result" when the execution times out

[anthonyting]

Expected Behavior

A better error message that the execution timed out instead of a generic missing error result.

Actual Behavior

The error reported is "Could not find error result" which is not clear

Steps to Reproduce

1. Create an execution that times out
2. Run with cloud runner
3. Execution times out
4. Calling getResult throws "Could not find error result" since ExecutionTimedOut doesn't have any error details
