Bug in tokens for price feed

[fhenneke]

Just saw this comment and in particular

The writing in the new tables is also based in the token imbalances token list, as this is more efficient (as we do not need prices for tokens with an imbalances of exactly zero).

This is not correct as imbalances do not account for network fees and protocol fees. Thus we need prices for them as well if we want to reproduce our current accounting.
