Fixes an audit finding. Report will be published soon.

The current implementation of the ERC2771Forwarder doesn't check that the msg.data has a length of at least the ERC2771 suffixed address, nullifying the result and producing the address(0) whenever accessing an out-of-bounds calldata location (i.e. calldata with size 19).

This PR checks for the correct length and falls back to the original sender.

Fixes LIB-984

I thought accepting a suggestion doesn't dismiss reviews, but it does.
Can you reapprove @Amxx?

For future observers, the title of this PR says <= 20 but it should have been < 20. The code does the latter (correctly).
