Tests failing when launched without data files

The trivial problems are fixed, the tests run well w/o data files apart of a few failures which are present also with data files present. These remaining failures must be checked / fixed:

bugs fclasses bug7287_3 bug7287_4 bug7287_5 bug22611
bugs modalg_1 buc60898
bugs vis bug23226

1. bugs fclasses bug22611
QA command OCC22611 was added to QABugs_19.cxx, TODO was deleted, test case is OK.

2. bugs modalg_1 buc60898
I modified name of shape and moved test case to folder moddata_3 to avoid checkshape in end file. Test is OK.

3. bugs vis bug23226
Test case was modified using function checkcolor. Test is OK.

Branch is ready for testing.
