Refactoring EVM python tests for py.test

[gigimon]

Rewrite neon-evm python tests for py.test based on neonlabsorg/neon-tests#31

Remove:

1. test_acc_storage_states.py
2. test_event.py
3. test_rw_block.py
4. test_transaction.py

Move to proxy:

1. test_block_hashes.py
2. test_delete_account.py
3. test_deploy.py
4. test_eth_token.py
5. test_nested_call.py
6. test_solidity_precompiles.py

Remaining tests rewrite:

1. Use py.test for run tests
2. Remove copy-paste
3. Rewrite tests for using new transactions (remove begin/continue instructions)
4. Fix ci/cd scripts and build

New tests:

1. Tests for account block (using PartialCallOrContinue, ExecuteTrxFrom instructions):

• operator can write to account
• operator can't write if account blocked
• another operator can't write to blocked account
• operator can write after unlock

2. Tests for Deposit (neon tokens from solana to neon-evm) - another task

• deposit neon/spl tokens
• can't deposit more than exist

3. Solidity events - in another issue (when new events and logs will be realized)
