There is no longer any reason for these to be intertwined.
This deliberately avoids touching some files as much as possible because
they are super tangled and due to be replaced. Those files are:
* fdroidserver/build.py
* fdroidserver/update.py
# Conflicts:
# tests/testcommon.py
# Conflicts:
# fdroidserver/btlog.py
# fdroidserver/import_subcommand.py
When troubleshooting things that are difficult to reproduce locally, like
different behaviors in the fedora_latest job, these changes make it easy to
keep the test files around after the tests run. For example, if PNGs are
processed differently by newer Python versions.
