cli_wallet core dumps when cli_wallet -v is used

Behaviour is shown below:

bunker@son-hive:~/peerplays-testnet$ ./cli_wallet -v
terminate called after throwing an instance of 'boost::exception_detail::clone_impl<boost::exception_detail::error_info_injector<boost::program_options::unknown_option> >'
  what():  unrecognised option '-v'
Aborted (core dumped)

Expected behavior:

When a non-existent value is passed on to the program as command line argument, it should not crash the program but it should be handled.
