CodecService fails correctly encode multiple entries in keyless list

[ygorelik]

Expected Behavior

The CodecService must correctly encode keyless list with multiple entries.

Current Behavior

The CodecService fails encode keyless list of leafs when the list contains multiple entries. The encoded string (JSON or XML) contains only one list entry.
