fix(importing): make document receivers/tags canonical-authoritative on re-import

Browse Source 
The DocumentImporter accumulated receivers/tags via addAll without pruning, so a
shrunk canonical row left stale links on a re-imported PLACEHOLDER document. Clear
the collections before re-populating so the canonical row is authoritative: a removed
receiver/tag is now pruned. Raw sender_text/receiver_text retention is unchanged.
