fixed the interface to string conversion error

[THasthika]

There was an conversion error when adding existing torrents to deluge, so I wrapped the conversion into a separate function tryParseResult.

Thanks for looking into this.

Do you happen to know what is the actual type that was returned? It is really weird that it was not a string. Can you add some logging so at least we know what it is when it happens?

When adding a magnet link which is already in deluge, the response is as below

map[id:2 result:<nil> error:<nil>]

The id is OK, but the result is nil as does the error.
