fix add check before trying to access yoast data store

[fabiankaegy]

Description of the Change

Currently, the Yoast SEO plugin does not expose their data store in the site editor. (See Yoast/wordpress-seo#20473) Therefore the usePrimaryTerm hook currently produces a JS error when called in that context since all the other checks are passing. (The plugin is active and the taxonomy is supported). This adds a simple check for the existence of the data store before trying to call the selector.
