Subject: [PATCH] Set active snapshots in multi-xact index create

Set active snapshots when creating txns during index
create with timescaledb.transaction_per_chunk. This
is needed for some index types like `bloom`.

Tests not added since we don't want dependencies on contrib modules
like bloom.

Fixes #1521.
