- in Tool Follow made sure that the resulting geometry elements are all valid and not empty and also do not contain Points as those are irrelevant in the Follow Tool

- in Geometry Editor fixed the selection on the Geometry Table
- in Geometry Editor - made sure that the edited Geometry do not contain Shapely Points and that when adding shapes, that the geometry of that shapes is valid and non empty and it is not a Shapely Point
- in Geometry Editor - added new information's (length, coordinates and vertex points number) for the geometric element selected in the Geometry Table
