Cannot materialize nested ADTs by a single call of GenCodec.materializeRecursively

[plokhotnyuk]

Currently, if a field of the top-level ADT has reference to another ADT, than both ADTs should be materialized recursively.
Please, see the following line for a use case: https://github.com/plokhotnyuk/jsoniter-scala/pull/127/files#diff-23a38b9df42d1a3a0e654c5532d6f666R37

Looks like it's an omission in flat sealed hierarchy codecs (the ones that use @flatten annotation) which also involve recursive types. Will be fixed in next version.

Fixed in 1.28.0
