Safety check for python version in get_pip_command
We know empirically that some legacy gate jobs pass and appear
to be running with python3 but actually pip was invoked with
PYTHON3_VERSION unset so that they are actually ran with python2
packages.
As a followup to this discussion [1], add a safety check in the
get_pip_command function to ensure that a python version has been
set when it is invoked.
