 Seems like I missed a few. The error caused in # was terminating the build
 after the first `phpunit` command was run. This caused multisite and AJAX
 tests to not be run. While working on fixing #, two more instances of
 showed up.

 In WP_Site_Query, `$groupby`, and `$limits` can also be undefined when
 `compact()` is called.

 To see the [https://travis-ci.org/WordPress/wordpress-
 develop/jobs/445930152 new warnings, you can check out this test build].
