[EVM] Refactor emulator test nonce tracking

[sideninja]

Right now emulator tests rely on test account nonce which is tracked globally and this means if a test is run independently it might fail because it relies on nonce being updated by others and vice-versa.

Example see: https://github.com/onflow/flow-go/pull/5614/files/7ef18932a517b3523b1a86ad30c3494b1d84749f#diff-759752553abf911832d94d89fd906fe87038d8816fdad2f2a1cd02e2574c61e5R308
