[api] panic while accessing an object on nil when signing an ethereum transaction

[florianlenz]

Problem

When Panthalassa send request to send ethereum transaction to Pangea, Pangea sends back an error (on transaction cancelling).
This data is sent to PanthalassaSendResponse method:

{
    data = "";
    id = "1fbce65d-3c53-4078-bed8-de0346ca512b";
    responseError = "";
    timeout = 20;
}

The result is that app is crashed right away with that stack trace:

Expected

Expected app to not crash and handle error response correctly.

Note

Panthalassa version is from commit 5ef8980.
