Bugfix: Ignore ContractLogicError raised by Web3.py

[FeSens]

Streaming a recent blockchain contract, I've received the error below, and the streaming got stuck in a retry loop. As per issue #143, it should be safe to ignore.

Further explanation:

The contract that raises the error is this one: https://etherscan.io/address/0x60ff650143d3fcd98585ce60a9a622f255ce5687

Not sure if other people had this problem while streaming data. It appears that sometimes the code hangs in a retry loop, and sometimes it does not.

The modification that breaks the code happened two years ago in the Web3.py dependency after the EthTokenService was written, and the issue was closed.

I also get these errors when export_all data. it's a critical issue that will break the whole process. thanks for this PR

[charlesAuthentik]

Same here.. Seeing the same issue when running export_all from block 3600000 to 3800000

@medvedev1088 can you give it a look?

[medvedev1088]

Thanks @FeSens. Released in v2.0.3
