Replaced loadConfiguration(0) call removed in 9bc1151811f9d059d4a0e591e42165c8e7edb36f

This was originally causing a bug by which scopes were loading variables twice, so was removed. However, the scopes bug was fixed during the refactoring, and so this call needs to be put back in order to avoid bugs such as https://github.com/TauLabs/TauLabs/issues/394

It would be nice to understand why some gadgets require this loadConfiguration(0) and others do not.
