* accounts/abi: fix various issues The fixed issues include: (1) If there is no return in a call function, unpack should return nil error (2) For some functions which have struct array as parameter, it will also be detected and generate the struct definition (3) For event, if it has non-indexed parameter, the parameter name will also be assigned if empty. Also the internal struct will be detected and generate struct defition if not exist. (4) Fix annotation generation in event function * accounts/abi: add new abi field internalType * accounts: address comments and add tests * accounts/abi: replace strings.ReplaceAll with strings.Replace
