Calls to mt_immutable_timestampt/mt_immutable_timestamptz fail with duplicated fields

[cocowalla]

Similar to #837, after upgrading Marten I'm getting the following error message when updating a type with a duplicated column:

schema "public" does not exist

I can see a statement being executed like:

update myschema.mt_doc_mytype as d set message_timestamp = public.mt_immutable_timestamptz(data -> 'Message' ->> 'Timestamp') where (d.tenant_id = :tenantid and d.id = :arg9)

^ Note the public.mt_immutable_timestamptz - also note that when creating my document store I am setting DatabaseSchemaName = myschema.

The problem seems to be here in DuplicatedField - a new, default StoreOptions is being created, instead of using the configured one.

Will send a PR for this shortly

Letme know if you need help to try something.
(sorry for not coming up before, was on a very tight spot with work)
