Title: Fix wercker url case problem

## The problem

When `WERCKER_URL` is exported on Mac OS the value isn't used by the CLI. Only when you export it lower case.

## Solution

Changed `config.py` to check both cases.

## Side effect
The fix broke some unit tests when my wercker_url env var was set. I fixed the unit tests by let them deleting both cases. Which feels kind of ugly.
