Problem: internal EVM call don't fail if the method is not implemented

which causes a serious issue in token mapping, if the mapped contract lacks the `mint_by_cronos_module` method, then when converting tokens, the native tokens will disappear, and there are no equivalent crc20 tokens minted.
we better check the `Transfer` event in the returned receipt logs.

Trace the internal EVM call used during token mapping and inspect the returned receipt logs, focusing on the Transfer event. Done means a mapping with no mint_by_cronos_module method does not silently consume native tokens and only treats the conversion as successful when the expected CRC20 mint transfer is present.
