    extensionSystem: Fix an error related to extension importing
    
    If an extension fails to import, we will pass the error object
    to logExtensionError, which fails to pass it onto DBus as an
    error object is not a string. To fix, convert the error object
    to a string before passing it to logExtensionError.
