Queue.py Fixes
Created by: marcus-oscarsson
The problem is that sample_id is a number when a new sample is added manually and there is nothing that prevents us from using the NEW SAMPLE control in the queue when use_sc is true.
We consequently try to split a number, which of course will fail.
This should maybe be handled differently and the original problem will disappear if/when the NEW SAMPLE control is removed from the queue. I simply but a simple log message to notify us about a potential problem.
