php7.3 compatibility: Fix compact throwing notices for multisite 

In PHP 7.3, the compact() function has been changed to issue an E_NOTICE level error if a passed string refers to an unset variable. In previous versions of PHP, this notice was silently skipped. The full RFC can be viewed here: https://wiki.php.net/rfc/compact

By initializing these variables, they can be compacted.

Previously [43819].
See #44416.
Props desrosj.
