Taxonomy: Specify taxonomy when populating cached object terms.

[38776] introduced a call to `get_term()` using only the term ID. This
causes problems in cases where shared terms have not been split. Since
we have the taxonomy available, there's no harm in passing it along to
`get_term()`.

Props dd32.
See #37291.
