Radosław Piliszek 29bf852396 Do not try finding pip for python2 when not required
[1] stopped installing pip for py2 when py3 is being used.

This patch makes sure we check only for py3 pip then.

Also removed some no-longer-relevant comment and
made uninstall behave the same.

Check for pip>=6 removed too.
