fix(7281): remove the string "DRAFT_MEDIA_FILES"

[bitgroestl]

Summary

This fixes #7281.

I simply removed the string DRAFT_MEDIA_FILES from the return value of selectMediaFolder and the issue disappeared. I have no idea why this string existed in the first place, but i highly advise that someone with more insight takes a look at this PR in case it breaks anything.

Test plan

I updated the corresponding test to reflect how i think this should work. npm run test doesn't show any failures.
