Imagine the following scenario:
1. SELECT COUNT(DISTINCT(filepath)) FROM `ezimagefile`; gives 20 000 results.

2. SELECT DISTINCT img.contentobject_attribute_id, img.filepath FROM `ezimagefile` img gives 120 000 results.

3. The number of iterations will be equal to 20 000/100 = 200 - https://github.com/ezsystems/ezpublish-kernel/blob/7.5/eZ/Bundle/EzPublishCoreBundle/Command/NormalizeImagesPathsCommand.php#L232, 100 is taken from the constant.

4. As each iteration fetches 100 records (https://github.com/ezsystems/ezpublish-kernel/blob/7.5/eZ/Bundle/EzPublishCoreBundle/Command/NormalizeImagesPathsCommand.php#L237) the total amount of processed pairs would be equal to 200*100=20000 but the number of results from step 2. requires 120 000 processed results.

Result:
Not all of the image paths will be processed.

Expected result:
All paths should be processed in one go.
