Unable to use `schema` on `Table`

[Aaronzinhoo]

Checklist

• [ x ] I have included information about relevant versions
• [ x ] I have verified that the issue persists when using the master branch of Faust.

Steps to reproduce

When using the Table apply a schema parameter and try to pass in a custom serde

Expected behavior

The custom Schema passed to the Table would be used rather than the default json value serializer.

Actual behavior

Default value serializer was used
