Fix precommit issue between black and flake

[mmeendez8]

Code to reproduce:

    image_0[
        int(image_0_bbox_top) : int(image_0_bbox_top + image_0_bbox_height),
        int(image_0_bbox_left) : int(image_0_bbox_left + image_0_bbox_width),
    ] = 0

Output:

flake8...................................................................Failed
- hook id: flake8
- exit code: 1

tests/apps/test_paint_annotations.py:137:30: E203 whitespace before ':'

Black is adding extra whitespaces that do not match with flake8 config
