sqlState is not working anymore for PostgreSQL

[mobiletoly]

This code used to report sqlState correctly in version 0.10.2 for PostgreSQL database. Now it is broken in 0.10.3

   try {
        Listings.insert {
            it[Listings.id] = listing.id
            it[Listings.providerUserId] = listing.providerUserId
            ...
        }
    } catch (ex: ExposedSQLException) {
        throw when (ex.sqlState) {
            "23505" -> RequestedListingAlreadyExistsException(listingId = listing.id)
            else -> ex
        }
    }

in case when Listings.id violates a constraint (duplicate). Now ex.sqlState is always null (as well as ex.errorCode is 0).

Now ExposedSQLException will delegate its sqlState and errorCode to an original exception if it was an instance of SQLException.
