Update all tests to the latest framework's API

[m-Peter]

The latest flow-cli release (v1.5.01) includes quite some changes to the API.

This is interesting! Curious about how we determine the testing address and how the testing alias is used

Hey @sisyphusSmiling 👋
Basically, I borrowed an idea from Flow Playground, where we use simple, sequential addresses to be easier to deal with. The testing framework now offers a pool a 10 predefined accounts, where users can deploy their contracts under testing.

import Test
import BlockchainHelpers
import "ApprovalVoting"

access(all) let admin = Test.getAccount(0x0000000000000007)

access(all)
fun testInitializeEmptyProposals() {
    let txResult = executeTransaction(
        "../transactions/initialize_proposals.cdc",
        [proposals],
        admin
    )
}

Developers can also gain access to this account, in order to use it for signing transactions.
Stay tuned as I am going to update all relevant projects with the new API, including HybridCustody
