[server] fix deserialize_schema to handle properly pg schema (closes 17076486)
Postgres behaviour is to look first for a table in the configured schema then
fall back to 'public' if no table is found.
This must be implemented in deserialize_schema when listing existing tables
to check for computed relations (cw_cwcomputedrtype) otherwise computed
relations may not work when using non-default pg schema.
