Running a test with --node-arguments='--expose-gc' causes ERR_WORKER_INVALID_EXEC_ARGV

[dmaevsky]

npx ava tests/perf.spec.js --node-arguments='--expose-gc'

gives me

✖ Internal error
  Error [ERR_WORKER_INVALID_EXEC_ARGV]: Initiated Worker with invalid execArgv flags: --expose-gc

version 4.0.1

AVA uses worker threads by default. Looks like this is not an argument that can be passed to worker threads. You can run with --no-worker-threads (IIRC) to use child processes and then this should work.

I ran into this too trying to use --prof. Might be worth adding something to the docs about.
