Jenkins Repo plugin adds an "empty" change log when there is a
new project added or removed, e.g.:
path: local/path
serverPath: server/path
revision: null
authorName: null
authorEmail: null
authorDate: null
committerName: null
committerEmail: null
committerDate: null
commitText: This project was added from the manifest.
modifiedFiles: null
When Slack plugin tries to add the "null" affected files, it gets a
NullPointerException error.
Fix the error by not adding any empty affected files collection.
