cli: add test for --guessed-eventtypes RPC binding generator flag

Currently we have problems with unnamed structs used as a parameter for
notifications, because there's no one-to-one correspondence between
notification parameter and the list of extended types used by the whole
contract. Otherwise eventtypes guessing works OK.
