 In https://core.trac.wordpress.org/changeset/43555 some documentation was
 added for the `tests_add_filter` function. According the documentation the
 second parameter `$function_to_add` should be an `array` or an `object`:

 {{{
 @param object|array $function_to_add The function/callback to execute on
 call.
 }}}

 Should this not be changed to `callable`? Same as the `add_filter`
 function?
 https://core.trac.wordpress.org/browser/trunk/src/wp-
 includes/plugin.php#L99

 Scrutinizer is complaining about this:

 '_manually_load_plugin' of type string is incompatible with the type
 array|object expected by parameter $function_to_add of tests_add_filter().
