[MC-279258] Creating a sign with formatted text serializes lines without formatting incorrectly

Reproduction

/setblock <pos> oak_sign{front_text: {messages: [{text: "hello", bold: true}, {text: "a"}, {text: "b"}, {text: "c"}]}}

/data get block <pos> front_text.messages

Expected

The data get returns

[{text: "hello", bold: true}, {text: "a"}, {text: "b"}, {text: "c"}]

Observed

The data get returns

[{text: "hello", bold: true}, {"": "a"}, {"": "b"}, {"": "c"}]

with the key that's supposed to say text being an empty string instead.

Can confirm.

This is caused by the game using empty key notation like that to make lists of mixed types. It is attempting to simplify the first element's text component to a compound, but the other 3 lines simplify their text components to a string. When the game inserts a string into a list of compounds, it wraps the string in a compound and puts it in an empty key.
