Launch=false not respected

[silvercross313]

Repro:
(Note: I am using Testium to sanity test the Groupon Getaways prod site, so I have launch=false in my .testiumrc file and I don't want to be launching anything. I'm testing against groupon.com, so I don't need to launch anything. I am using Testium 3.3.1 and Testium-core 1.4.5.)

1. Run the prod sanity tests.
   Expected:
   The tests run successfully.

Actual:
I get an error about 90% of the time that says:
"Failed to initialize WebDriver. Check phantomjs.log.
Checking port 4445:
listen EADDRINUSE
