chore(layer): fix bundling and e2e tests by manually setting hash of asset

[flochaz]

Description of your changes

For some reason bundled layer was not updated properly when version change.
After some investigation it looks like to be related to a bug in lambda.Code.fromAsset which does not take into account a change in bundling local command. Forcing the calculation of the hash based on bundling local command (which include version as well), layer is updated properly.
