test(wallet): creates a unique wallet for each spec for each run

[ygrishajev]

This PR introduces a tests wallet setup for functional tests. This should solve 2 issues:

1. account sequence mismatch issues when running same tests at the same time
2. once we have a pg db generated for each run we'll be able to run tests in parallel and improve run time

Before each run:

1. it generates a local faucet wallet
2. fills it via sandbox faucet
3. generates a unique wallet for every functional spec
4. sends tokens from local faucet wallet to spec wallets
5. sets spec wallet mnemonics in env
