deleteOwnPost() can't be reused at the moment

[Howard-Zhou]

deleteOwnPost() uses the global courseId within the course view, however, the same method cannot be applied when a user wants to delete posts from other courses within the same course view.

for example, right now I'm inside CPEN 321. I can delete any post within CPEN 321, however an error would occur If I want to delete a post from APSC 481.

Do not have enough functional brain cells to think of a smart alternative to implement both
deleteOwnPost() and deleteUserOwnPost() right now
