Tellraw Parsing Issues

[JeffreyGaydos]

• /tellraw @s [{"text":"Dialogue1"},{"text":"Dialogue2"},...] is now valid syntax, and should be the preferred default
• Any kind of empty object that is still valid JSON causes the parser to fill certain values with undefined
  • for example: /tellraw @s {"text":"__","extra":[{}]} will render as __undefined
