Danger apparently has three different objects which could contain files
you often want to check:
- git.added_files
- git.modified_files
- git.renamed_files
The problem: If a file is renamed, `modified_files` contains the file
path before the rename. In some Danger checks we use `added_files` +
`modified_files`, which might contain the deleted paths of renamed
files, but missing the new paths of renamed files.
So we need to consider `renamed_files` as well.
