Failed with GitLab CI

[artemklevtsov]

I tried to use lintr for the package testing with the GitLab CI. I got the following error:

$ Rscript -e 'lintr::lint_package()'
Error in httr::status_code(response) : object 'response' not found
Calls: <Anonymous> -> print.lints -> github_comment -> <Anonymous>
Execution halted

Now ci_type() support only Travis CI and Wercker CI on Github.

Seems reason of the error in the following rows:

• https://github.com/jimhester/lintr/blob/a769c0b8be6740329d8d855f230e6ff3c31175c1/R/methods.R#L60
• https://github.com/jimhester/lintr/blob/a769c0b8be6740329d8d855f230e6ff3c31175c1/R/methods.R#L70

I find a simple workaround: to unset CI environment variable.

I have this same issue in CircleCI 2.0. Adding export CI="" before the lint step also worked for me.
