Logfire only shows pretty message log when using prompt_template

[off6atomic]

Description

Run the following code:

import logfire
from dotenv import load_dotenv
from mirascope.core import openai, prompt_template
from mirascope.integrations.logfire import with_logfire

load_dotenv()
logfire.configure()


@with_logfire()
@openai.call(model="gpt-4o-mini")
def recommend_book_bad(genre: str) -> str:
    return f"Recommend a {genre} book"


@with_logfire()
@openai.call(model="gpt-4o-mini")
@prompt_template("Recommend a {genre} book")
def recommend_book_good(genre: str): ...


print(recommend_book_bad("fantasy"))  # ugly log
print(recommend_book_good("fantasy"))  # pretty log

And you will see the following ugly log on logfire:

This one is prettier log:

The only difference between them is the existence of prompt_template decorator in the 2nd function.

How can we make the log pretty for the 1st function as well?
I like to write in style of first function more because is more explicit and less magic.

Sorry @willbakst, lots of bug reports lately.
