Test suite: Add a transaction with assets.data field present to the test blockchain

[MichalTuleja]

The original test blockchain is missing a transaction featuring the assets.data field.
The aim of this issue is to add such a transaction for a better test coverage.

Modifying the e2e-test-setup.sh and using the lisk-commander command-line tool may be the easiest way to achieve that.

UPDATE: This should be an update to the test blockchain that contains data field and at least one multisig account.

After the discussion with @lsilvs the decision was made not to include it in the current version.
The extended test suite will be applied in the Lisk Service repository.

After a quick chat with @fchavant, this snapshot contains the required transactions. It will be tested during the test suite update mentioned in #844.

The extensive tests will be implemented in the new Lisk Service backend.
