Fix frame of `GDBThreadSelectedEvent` if inferior is running When ifnferior is running at time we get `=thread-selected` event, we should at least make that frame kind of usable by fixing up it's debugger and thread. This allow clients to use (to some extent) event's frame without worring (too much) about these details.
