Puppet Module Tool Does Not Honor puppet.conf Settings unless they are in [main]

When setting the environmentpath setting and basemodulepath setting if you place them in the [master] section of puppet.conf then `puppet module list` will not work correctly.

If you place both settings in [master] then you just get the default modulepath returned from `puppet module list`.

If you place just basemodulepath in [main] and environmentpath in [master] then `puppet module list` will return the basemodulepath.

If you place both settings in [main] then `puppet module list` works as expected.
