Fix: upgrade fails if existing venv was created with symlinks (#2489)

Browse Source 
if reinstalling over an existing installation where the .venv was
created with symlinks to system python instead of copies of the python
executable, the installer would raise a `SameFileError`, because it
would attempt to copy Python over itself. This fixes the issue.

Copying the executable is still preferred for new environments, because
this guarantees the stable Python version.
