[PLAT-8386] Fix test flake in in LastRunInfoScenario

[nickdowell]

Goal

Fix an occasional test failure in features/last_run_info.feature:6 / LastRunInfoScenario.

Sometimes one of the And I wait to receive an error steps would fail because the fixture crashed before the previous run's payload was sent.

This scenario relied on config.sendLaunchCrashesSynchronously for payloads to be sent before crashing the fixture, but in some cases due to a slow network connection 2 seconds (which is as long as Bugsnag.start() will wait) is not enough.

Changeset

Ensures crash reports have been sent before triggering another crash.

Testing

Was unable to reproduce this artifically / verify the fix.

Maze Runner's I set the response delay to {int} milliseconds step does not reproduce the failure because it does not prevent the request being fully received by the server within the 2 seconds.
