Failed unit test pipelines may be marked as successful

Description

Because of an issue with istanbuljs/nyc it's possible that failed unit test runs are shown as passing in the CI, for example if a JavaScript heap out of memory error occurs.

Here's the issue that tracks the bug upstream https://github.com/istanbuljs/nyc/issues/798 The current issue is related to #2300

Steps to reproduce

1. Create an example test file

   echo "var x = []; while(true) x.push({ a:'123'.repeat(1000000) });" > test.ts
   

2. run npx nyc ts-mocha --max-old-space-size=16 test.ts
3. Check the exit code echo "Exit code: $?"

Expected exit code is 134, but the actual is 0
