Taxonomy: Avoid duplicates when querying for terms in taxonomies registered with $args parameter.

Browse Source 
[40514] introduced a bug that caused term queries to return some duplicates
when the `$taxonomies` array contained only taxonomies that were originally
registered with an `$args` array. We fix this bug by ensuring that
recursive `get_terms()` queries stop when all queried `$taxonomies` have
already been referenced.

Ports [41037] to the 4.8 branch.

Props bor0, atanasangelovdev.
Fixes #41010.
