Message:

Taxonomy: Prevent non string taxonomy names generating warnings or errors.

This changeset adds an is_string( $taxonomy ) check to the condition in taxonomy_exists(), to ensure false is returned when the $taxonomy is not a string.

Follow-up to [35718].

Props costdev, peterwilsoncc, mukesh27.
