Remove residual problems

[y19880621]

In xrtQook gui, after removing a renamed "screen" by right click menu and running again, there occurs an error as follows:

Exception in thread Thread-1:
Traceback (most recent call last):
File "C:\Anaconda2\lib\threading.py", line 801, in __bootstrap_inner
self.run()
File "C:\Anaconda2\lib\site-packages\xrt\multipro.py", line 275, in run
raycing_output = raycing.run.run_process(self.card.beamLine)
File "D:/OneDrive/Codes/XRT/test/Beamline/NanoProbe/StepByStep.py", line 153, in run_process
'Screen_tmp1_BeamLocal': Screen_tmp1_BeamLocal}
NameError: global name 'Screen_tmp1_BeamLocal' is not defined

Then I checked the ".xml" file and found that the "Screen_tmp1_BeamLocal" still existed under . After deleting that line, the program runs properly.

... still existed under " Beams type="prop" ".

Thanks for the feedback, the bug should be gone now.
