Do not use pip cache, fix coala warning

Builds have been failing due to using some very old cached versions
of dependencies. By using --no-cache-dir, we force pip to pull in
up-to-date versions of all dependencies.
This also includes a change to language that caused tox to fail due
to a coala warning.
