EVM token split: intrinsic.migrateToken does not create tokentransfers

[kuegi]

Summary

when using the migrateToken function on the intrinsic SC, it directly replaces the balances in the DST-20 contracts, but no token transfer is created. so looking at the logs, there is no trace of the split.

Better we add a burn of the old token and mint of the new token to the logs. Otherwise I guess that trackers geht confused/messed up.

Environment

• Node Version: 4.1.0-alpha

Thanks for this report @kuegi. This is indeed something to cleanup.

@Jouzo is currently working on a refined iteration of the handling on the EVM layer.
