Fix loading bar going out of bounds (#688)

The actual reason lies in the loader implementation, which for some reason can sometimes count up the `m_refreshedModCount` twice for some mods which are disabled.

This small change checks the actual loaded mod count instead of relying on an incorrect `LoaderImpl` member and fixes issue #687.
