Error description when creating identity with web3url sent as null

[rauljareno]

Right now, when sending null value to the web3url parameter passed to create an identity, the method is returning an error with a description that gives information of how the method is working internally (ethclient, dial unix, missing address...) I think this error should be more generic to the integrator and just inform that the web3url parameter sent is not valid

Iden3mobile.newIdentity(
"$storePath/alias",
"password",
null,
1000,
null
) { event -> print(event) }

Result -> "Error dialing with ethclient: dial unix: missing address"
Expected -> "There was an error connecting with the web3url sent as parameter. Please, check it and try again"
