#2899: Various chat API stability updates

- Check if a value CAN be parsed as a BaseComponent[] before attempting to parse it through the Content deserialiser
- When removing enclosing quotes from deserialised NBT, don't remove all quotes as they may have been escaping
- Check for ALL the number suffix types
- Throw JSONParseException if: no selector in selector component, no translate in translate component
- JsonObject is not JsonPrimitive
- Cleaned up unit tests a bit
