coho audit-license-headers issues in cordova-fetch

coho audit-license-headers -r fetch uncovered the following text files without a valid license header:

• spec/support/dummy-local-plugin/plugin.xml
• spec/support/repo-name-neq-plugin-id.git/HEAD
• spec/support/repo-name-neq-plugin-id.git/config
• spec/support/repo-name-neq-plugin-id.git/refs/heads/master

On the 1.3.x branch this issue only shows up in spec/support/dummy-local-plugin/plugin.xml at this time.

Recommended solution is to add standard header to spec/support/dummy-local-plugin/plugin.xml and add the other files to .ratignore.
