Fix bug with repeated calls

Otherwise was adding every time since we reset stuff for `job` not `self` different.
Felt smoother to align with all being job object to help maintain context since the array `attached_directories` was already reset above

Prior output example:
Directory ID: 9693       Schema ID: 3665
{'attached_directories_list': [{'directory_id': 9693, 'selected': 'sync'}]}
Directory ID: 9695       Schema ID: 3666
{'attached_directories_list': [{'directory_id': 9693, 'selected': 'sync'}, {'directory_id': 9695, 'selected': 'sync'}]}
Directory ID: 9697       Schema ID: 3667
{'attached_directories_list': [{'directory_id': 9693, 'selected': 'sync'}, {'directory_id': 9695, 'selected': 'sync'}, {'directory_id': 9697, 'selected': 'sync'}]}

New example:
Directory ID: 58         Schema ID: 12
{'attached_directories_list': [{'directory_id': 58, 'selected': 'sync'}]}
Directory ID: 60         Schema ID: 13
{'attached_directories_list': [{'directory_id': 60, 'selected': 'sync'}]}
Directory ID: 62         Schema ID: 14
{'attached_directories_list': [{'directory_id': 62, 'selected': 'sync'}]}
