#201 delete photo tag (Fetch more recent codebase)

[dsyamy]

Old branch wasn't letting me fetch new codebase so had to make a new one.

Pull Request

Brief Summary

• Fixed the path for the photo model as it was causing issues.
• authorization of tag deletion is given to admin and photographers.
• Included the cascading effect of photoTag deletion, but only to Photo at the moment (since it's the only model that references photoTag, but future models with references can be added to referencesToPhotoTag in photoTagAccessor.js
• provided 3 tests: 1 proper deletion, 1 improper deletion (tag does not exist), 1 proper deletion with cascading effect

Looks mostly good. My only issue is the double call to the accessor seems unnecessary.

For the ErrorPhotoTagNotFound(), I opt for a nested try-catch in the controller bc wasn't sure if throwing it in accessor would be bad design, but if not, I can edit again.
