UUIDField ignores primary_key=False when generating migrations or SQL

[xjlin0]

Problem

UUIDField with the option of primary_key=False got reverted to primary_key=True in generated migrations or SQL.

Environment

• Django Model Utils version: 4.2.0
• Django version: 3.2.11
• Python version: cPython 3.9.10
• Other libraries used, if any: with Cookie cutter Django version 2021-10-26

Code examples

Including a UUIDField with primary_key=False in a model:

test = model_utils.fields.UUIDField(primary_key=False, default=uuid.uuid4, editable=False, serialize=False)

Surprisingly, when running migration it becomes primary_key=True:

field=model_utils.fields.UUIDField(primary_key=True, default=uuid.uuid4, editable=False, serialize=False)

as well as generated SQL:

CREATE TABLE table_name ("test" uuid NOT NULL PRIMARY KEY ....

If the model already got primary key column, it's a headache to find workaround.

Expectation

UUIDField with the option of primary_key=False should keep primary_key=False in generated migrations or SQL.
