Themes: Avoid a PHP 7.2 warning in `get_theme_roots()` when `$wp_theme_directories` is an uncountable value.
See [41174] for `wp_get_themes()` and `get_raw_theme_root()`. Props burlingtonbytes, teddytime, lbenicio, desrosj. Fixes #43374. See #40109. Built from https://develop.svn.wordpress.org/trunk@43039 git-svn-id: http://core.svn.wordpress.org/trunk@42868 1a063a9b-81f0-0310-95a4-ce76da25c4cd
