mkinit removes __ignore__ under certain circumstances

[alessio-locatelli]

Describe the bug

Depending on the __ignore__ variable position it can be kept or removed.

To Reproduce

🟢 No problems (__ignore__ variable survives in the file):

# Some text here.
__ignore__ = ["spam", "eggs"]
__protected__ = ["foobar",]

# Some text here.

__ignore__ = ["spam", "eggs"]
__protected__ = ["foobar",]

# Some text here.

__ignore__ = ["spam", "eggs"]

__protected__ = ["foobar",]

__ignore__ = ["spam", "eggs"]
__private__ = []

# Some text.

__ignore__ = ["spam", "eggs"]
# Some text.

🔴 __ignore__ is removed by mistake:

# Some text here.
__protected__ = ["foobar",]
__ignore__ = ["spam", "eggs"]

# Some text here.
__protected__ = ["foobar",]
__ignore__ = ["spam", "eggs"]

# Some text here.
__ignore__ = ["spam", "eggs"]

__ignore__ = ["spam", "eggs"]

__protected__ = []
__ignore__ = ["spam", "eggs"]

Expected behavior

Always keep __ignore__ when it is around the top of the file.
