SANS error processing -add data

[Gesner Passos]

The ticket #8052 introduced a problem, that makes the reduction fail to processed files.

from mantid.simpleapi import *
from mantid import config
import ISISCommandInterface as ici
ici.LOQ()
ici.Detector("main-detector-bank")
ici.Set1D()
ici.MaskFile('MASK.094AA') 
ici.AssignSample('LOQ80047-add.nxs')

Reproduces the problem.

re #8156: Does not try to find file path twice

The _data_file is already a full_path in this stage. It is useless, and, as showed, error_prone to try to do it.

re #8156 correct getFilePathFromWorkspace

It could be different, but it is necessary to wait to fix #8158.

Windows uses backslashs for path, change it to forward slashes before comparing paths.

LOQSANSUtility: correct problem with MAC OS

I do not quite know why, but Mac is reporting that the file was saved as -ADD. So, it checks to change that, because, it does allow to load the file with that name as well.

The file where the problem was first viewed is inside ndxloq/user/processed.

Tester:

Run the script again and check that it is now correct. Besides, a branch with the same name (bugfix/8156_assign_processed_data) was created for systemtests to ensure that this problem does not repeat. Rembembe to update both mantid and systemtests.
