bus/call: Clarify error sources

There is some confusion, likely created by me, that call() might not
throw an exception in the case of a method call returning a
METHOD_ERROR.

This commit clarifies that all errors are thrown, and that we do not
need redundant is_method_error() checks on the reesulting message.
