EXIST() returns incorrect result when used as coordinate arguments to CONTAINS(GEOPOLY2D()) #4891

Bug description

What happened:
CONTAINS(GEOPOLY2D(...), latitude, longitude) correctly returns 1 for a point inside the polygon.

However, wrapping the same attributes with EXIST() causes CONTAINS() to incorrectly return 0:

What you expected to happen:
I expected these two expressions to return the same result:

CONTAINS(GEOPOLY2D(...), latitude, longitude)

and:

CONTAINS(
    GEOPOLY2D(...),
    EXIST('latitude', 0),
    EXIST('longitude', 0)
)

Since EXIST('latitude', 0) and EXIST('longitude', 0) return the same values as the underlying attributes, both should return 1 for a point contained by the polygon.

Steps to reproduce:

CREATE TABLE geo_test (
    latitude FLOAT,
    longitude FLOAT
);

INSERT INTO geo_test (id, latitude, longitude)
VALUES (1, 53.481319, -2.251460);

SELECT
    latitude,
    longitude,

    CONTAINS(
        GEOPOLY2D(
            53.3,-2.5,
            53.7,-2.5,
            53.7,-2.0,
            53.3,-2.0
        ),
        latitude,
        longitude
    ) AS direct_match,

    CONTAINS(
        GEOPOLY2D(
            53.3,-2.5,
            53.7,-2.5,
            53.7,-2.0,
            53.3,-2.0
        ),
        EXIST('latitude', 0),
        EXIST('longitude', 0)
    ) AS exist_match,

    EXIST('latitude', 0) AS exist_latitude,
    EXIST('longitude', 0) AS exist_longitude

FROM geo_test;

Expected:

direct_match = 1
exist_match = 1

Actual:

direct_match = 1
exist_match = 0
