Review comment:
The checks will warn (and therefor fail the build) if the DESCRIPTION
file doesn't include packages that we reference in the code, so this restores
the unedited file for checking.
Ultimately, we might not want to do anything with the editing, just use
caching to speed up the dependency installation but still install all of them.
But I was curious what the difference in time was + trying to get even the
first run as quick as possible at first
