utils: Fix bugs in DataObject encoders
The DataObject is some weird / rarely used different code than the
normal TLV encoder/decoder. It has apparently so far only been used
for decoding, without testing the encoding side, resulting in related
bugs.
Let's fix those that I encountered today, and add a test case.
