Custom plugins are not loading
Custom plugins are not loading as expected despite specifying them in init.toml.

## Expected behavior

Plugins must be loaded and expected behaviour must happen. E.g., templates must be loaded and initialized for template plugins.

## The reproduce ways from Vim starting (Required!)
