Detox: mocha: Detox interfers with .mocharc's "spec" property when Detox "specs" is not defined

Is your feature request related to a problem? Please describe.

It’s a bug(gy feature) of Detox.

If I specify the spec or files option in .mocharc.json

{
  "spec": "e2e/2_commandList.js",
  "timeout": 25000
}

and I don’t configure specs in the Detox config, relying on defaults:

Actual result:

The spec option clearly doesn’t work, because Detox overrides it with the default e2e value.

Describe the solution you’d like

Detox should not override ...specs with the default e2e value.

Describe alternatives you’ve considered

If I use the detox specs option in .detoxrc.json like this it works

But suppose if you have 10-20 test files, this wont be ideal to specify it in a string

  "specs": "e2e/init.js e2e/2_commandList.js",
