Revert "Set default people for reviews."

This reverts commit 766d1c9e3d52537be6985ab5eac32fcbe3df1ee2.

The TARGET_PEOPLE was applying on updates as well as new reviews. It looks like from a reviewboard perspective the only way to accomplish default people on new reviews is to use this functionality: https://www.reviewboard.org/docs/manual/2.0/admin/configuration/default-reviewers/.
