[7520] introduced an undocumented feature whereby developers could
register a custom taxonomy with an 'args' parameter, consisting of
an array of config params that, when present, override corresponding
params in the `$args` array passed to `wp_get_object_terms()` when
using that function to query for terms in the specified taxonomy.
The `wp_get_object_terms()` refactor in [38667] failed to respect
this secret covenant, and the current changeset atones for the
transgression.
Props danielbachhuber.
Fixes#40496.
