fix(tracing): race in stopChunk (#10481)
Consider the following scenario:
- Tracing is started.
- API call is made (e.g. page.waitForResponse), almost finishes, and
  enters onAfterCall where it starts a snapshot.
- tracing.stopChunk is called, and waits for existing actions to finish.
  However, it does so by calling onAfterCall one more time.
- tracing.stopChunk removes instrumentation listener and returns
  to the client.
- Client starts zipping files.
- Original API call finishes the snapshot and saves it to the trace file.

This results in trace file being written to while the zip is still working.
