Queries against functions with added arguments don't include the old calls

Steps to reproduce:

storage = Storage()

@op
def inc(x: int) -> int:
    return x + 1

with storage.run():
    z = inc(23)

@op
def inc(x: int, amount: int = 1) -> int:
    return x + amount

with storage.run():
    z = inc(23, 10)

df = storage.similar(z)
