Fixes an audit finding. Report will be published soon.
The current implementation of the ERC2771Forwarder doesn't check that the
msg.datahas a length of at least the ERC2771 suffixed address, nullifying the result and producing theaddress(0)whenever accessing an out-of-boundscalldatalocation (i.e. calldata with size 19).This PR checks for the correct length and falls back to the original sender.
Fixes LIB-984
