Improve Chat Component Legacy Serialization more

This brings chat componenent serialization to 100% accuracy so
that any text input in the legacy format, converting to comps and
then back to legacy will result in identical results.

If the user explicitly sets a color as prefix to a string, it is retained,
even if that color matches the default.

This also helps improve dealing with the empty string wrappers Bukkit creates.

A unit test has been added to verify this behavior.
