Enable slippage on all chains (#454)

This PR enables slippage computations on all chains.

It extends #447 to also pass the blockchain parameter to the slippage
query and log some results.

At the moment it uses query 4379621 instead of 3427730. This change can
be reverted once cowprotocol/dune-queries#87 is
merged.
