Taxonomy: Ensure that invalid term objects are discarded in WP_Term_Query.

Browse Source 
The `get_term()` mapping may result in term objects that are `null` or
`WP_Error` when plugins use `get_term` or a related filter. Since `null`
and error objects are not valid results for a term query, we discard
them.

Props GM_Alex.
See #42691.
