DefaultConversionService issue with enums

I noticed `DefaultConversionService#convert` uses `Enum#name` and not `Enum#toString`.
The issue with this in locations comes with how most conventions have enum constants be uppercased, while paths are usually lowercased.
Therefore, using `#toString` would let the developer decide for themselves.

Locate DefaultConversionService#convert and inspect how enum values are converted. Review the surrounding conversion behavior and existing tests before deciding how the requested enum string representation should work. Done means enum conversion supports the representation needed for lowercased paths and locations.
