Remove camel case from `imageuploadtype` in config

This removes the only camel cased option of the config options
**we** added to the config.json.

In auth provider's config parts are a lot of camel cased options
provided. We shouldn't touch them to keep them as similar as
possible to the examples.

Fixes #315
