get rid of Message-ID compression entirely

Provide a fallback for legacy SHA-1 messages, but do not
advertise shorter URLs anymore for data portability concerns.

This fixes a regression introduced in
commit 81a9c1b476987d845b340ab9013d26cf4487cb9a
("search: disable Message-ID compression in Xapian")
which ended up breaking thread-related endpoints for
large Message-IDs, as lookups on the SHA-1 message no longer
worked.
