Repro:

• two configs, A + B
• config A has a project enabled
• config B has no projects enabled
• config A and B share the same testDir
• I watch a test

This results in:

• TestServer.onTestFilesChanged gets emitted twice, from both configs. Since we consider both configs (Models) as enabled:

  playwright-vscode/src/extension.ts

  Lines 339 to 340 in 4a4b743

  	for (const model of this._models.enabledModels())
  	model.addToWatch(request.include, cancellationToken!);

• Emitted twice means the test ran twice

Thinking about a test.
