Add one of each transaction type to check_new_account_payment in test-agent.ml

[bkase]

We want to make the test-agent more powerful to ensure that operations are consistent within the mempool and block and make sense for all existing usercommands with the data-api and not just payments.

Specifically: In check_new_account_payment: Add new functions direct_graphql_delegation_through_block, direct_graphql_mint_token_through_block, etc for each user command. See the code reuse in construction_api_{payment,delegation}_through_mempool it may help with this bit.
