Name of wallet is incorrect.

I've used Gandalf@Mainnet for a wallet name, it's incorrect but I got that after finishing onboarding stage, i.e. it shouldn't let me use that name right away when validating input to the form.

result={'jsonrpc': '2.0', 'error': {'code': -32003,'message': 'Assert Exception:std::find_if(name.begin(), name.end(), !boost::algorithm::is_alnum() && !boost::algorithm::is_any_of("._-")) == name.end(): Name of wallet is incorrect.
