Test get_version_warning

This change is testing that get_version_warning():
- returns "" if current version is latest one
- returns a pre-release information if using pre-release
- returns a new release information and extra installation information.
  (note: this test doesn't check that guess_install_method() is working correctly)

I had to use pytest-mock to ensure that all test parameters are
correctly set. The test should not rely on current version (since it's likely
v1.2.3dev123) and on version on github.
