fix(benchmark tests): Ensure "benchmark end" event is emitted even if an error is thrown by the runner

[markfields]

Description

Fixes AB#55270

One of my benchmark tests fails intermittently with the error runtime benchmarks Non-Compat completed with status 'failed' without reporting any data.

This indicates that the "benchmark end" event was never emitted. I added a try-catch to see if that fixes it.
