fix(databases): set attributesUpdated on non-indexed attribute update path

When an existing non-indexed attribute was already present in
existingAttributes (existingIdx >= 0) and got replaced by the splice,
attributesUpdated was never set to true.  As a result the schemaVersion
bump and updatedAttributes() call at line 682 were skipped, leaving
downstream code with stale property resolvers when a plain field's
type/nullability changed via hot-reload.

The add path (existingIdx < 0) was already correct; this brings the
update path into parity.
