Daemon connection breaks because of a trailing "<"
When trying
```
let daemon = monerojs.connectToDaemonRpc("http://localhost:18081", "username", "password");
let height = await daemon.getHeight(); 
```
the console logs an error:

`SyntaxError: Unexpected token '<'`

I am sure it has nothing to do with my code, it only appears when pasting in the monero lib code.

Unrelated, but it may be worth investigating
`Needs multisig export info from more participants`
when syncing a 2/3 multisig wallet with just one _msInfo_, requesting to have the export ms data from both users when you actually just need one _msInfo_ to perform the operation.
