Make plugin VIP compliant by removing usage of `wp_remote_get`

[psorensen]

Is your enhancement related to a problem? Please describe.

The codebase currently contains instances of wp_remote_get which does not pass VIP's coding standards. #786 introduces a safe_remote_get helper function which uses vip_safe_wp_remote_get when available. Use this function to replace existing occurences of wp_remote_get.
