Description

When using the Materialized object if the user wants to name the statestore with

Materialized.as("MyStoreName")

then subsequently provide the key and value serde the calls to do so must take the form of 

Materialized.as("MyStoreName").withKeySerde(keySerde).withValueSerde(valueSerde)

If users do the following 

Materialized.as("MyStoreName").with(keySerde, valueSerde)

the Materialized instance created by the "as(storeName)" call is replaced by a new Materialized instance resulting from the "with(...)" call and any configuration on the first Materialized instance is lost.
