BrowserStackLocal process not finishes, if there are any test errors

[SlavikCA]

I'm starting BrowserStackLocal process via local.runner.js.
It works fine most of the cases.
But it any of my tests fails, such as this:

Response 500 POST http://hub-cloud.browserstack.com/wd/hub/session/1c2be4573b0441648ac6dc73fd8cf8a799f70915/element   
{ state: 'no such element', ...

Then I have 5 BrowserStackLocal processes running:

sfursov-mac:node1 sfursov$ ps aux | grep browsersta

And if I try to run tests again, I'm getting:

sfursov-mac:node1 sfursov$ ./local.runner.js --env chrome
Connecting local

until I kill all running BrowserStackLocal processes

Hm, I noticed, that issue reproduced, if Selenium error has status: 7
Not reproduced, if the error status: 32
