Testing post-receive-hook fails

Created by: kleinmann

Clicking "Test Hook" yields a 500 error on current master.

The error results from line 35 in hooks_controller.rb calling

@project.web_hook_data(commits.last.id, commits.first.id, "refs/heads/#{@project.default_branch}")

whereas web_hook_data now needs a fourth parameter author_key_id, as seen in models/project.rb, line 114.
