AutoConsumeSchema: use decode(payload, schemaversion) (apache#10700)

In `AutoConsumeSchema.decode `we should proxy the call to "`decode(payload, schemaversion)`" correctly to the wrapped Schema.

Even if the Schema is picked up from a map (`schemaMap`) that keeps track of the _schemaversion_, we must pass the correct `schemaversion` to the underlying Schema.

Some Schema implementations may fall back to using the "latest schema" if you pass "null" as _schemaversion_ or call `decode(payload)` (without _schemaversion_), leading to non consistent behaviour
