tests + fixes

[dorin-iancu]

Tests for all features.

• removed gas limit checks, as they're not needed, and only further complicate some checks.
• added check for token in balance. If we do have it, we don't need to check the roles
• slightly optimized to use references instead of cloning
• added check for batch_id in batch_transfer_esdt_token to prevent replay attacks
• increased default callback gas limit
