0024249: Crash on ShapeFix_Shape

Browse Source 
MAIN CHANGES:
FixAddNaturalBound: the boundaries of "natural bound addition" are restricted: a face, that does not contains an outer wire, should not have any infinite UV boundaries due to new face building (with using a surface) requires specified UV boundaries.
FixAddNaturalBound: myResult is updated in FixAddNaturalBound when the method creates a new face with natural boundary. myResult is required to be updated for next "fix small-area wires" algorithm
IsPeriodicConicalLoop: incorrect working BRepTools_WireExplorer was replaced on TopoDS_Iterator.
a natural bound is added to all the faces are constructed with UV-periodical surfaces (not only sphere and torus; e.g., closed b-splines)

other:
ShapeAnalysis: ReverceSeq renamed to ReverseSeq
BRep_Tool Pnt and Tolerance has the check for null TShape
Test cases for issue CR24249

required null checks were added
test cases were corrected according to their new behavior
