Replaced loadConfiguration(0) call removed in 9bc1151811f9d059d4a0e591e42165c8e7edb36f

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