Create a new tests for ERC20wrapped tokens

[gigimon]

ERC20Wrapped tokens - uses SPL token inside and we need a lot tests for this because in neonlabsorg/neon-evm#687 this system was refactored.

Test cases:

1. New possibilities (mint, burn)
2. Fixes a lot of cases when uses different actions in one transaction. We need a lot of cases for this, for example:

• mint, send, burn
• mint, send, send
• send, mint, burn
• send, mint, send, burn

3. When not enough gas for long transaction check that nothing changes
