coveralls debug insists that a token is required

[QuLogic]

Running debug mode does not print out anything:

$ coveralls debug
Missing .coveralls.yml file. Using only env variables.
You have to provide either repo_token in .coveralls.yml, or launch via Travis

Since the help says it won't send anything, one would think that the repo_token is not really required.

repo_token is optional for Travis CI, for other CI systems you can use env variable https://github.com/coagulant/coveralls-python#usage-another-ci

I am running debug locally. There's no need for a token; it's not going to be submitted anywhere.

I agree, I guess we can make repo_token optional for debug command, but keep warning message anyway.
