karmaRefresh cleaning entire node_modules folder

[borgiani]

Hi, when running the karmaRefresh task (which depends on karmaClean), the entire node_modules folder is being cleaned.
This is not very efficient in CI environments, because it causes the CI system to have to reload all node modules on every build.
By looking at the code, it seems the issue could be caused by: https://github.com/craigburke/karma-gradle/blob/master/src/main/groovy/com/craigburke/gradle/KarmaPlugin.groovy#L98

I'm guessing that replacing it with file should fix it.

Thanks!

@craigburke Adding this fix would be greatly appreciated! I have other libraries in my project, and it takes forever to do a fresh build because of this issue.
