Remove feature flag for suggest changes feature

Metrics tries to initialize the `EventsFinder` to instrumnt it. The `EventsFinder` tries to load the `Event` model, which in turn loads the `User` model.

Loading the `User` model requires Devise to be initialized. So to avoid problems around this, we load devise before loading metrics.
