Subject: [PATCH] test: install package before tests deps in unit_prev_versions
 (#703)

One of the test dependencies appears to require `rsa`, which resulted in a `rsa` version incompatible with 2.7 being installed.

Switching the order resolves the issue (`rsa` is installed according to the requirements in `setup.py`)
