Fix #162 - fix building master pipeline due to recent VTK upgrade in OpenSuse 15.

Master branch CI pipeline does not pass with VTK ver. 8.2. It stopped pasing right afer docker rebuild new images. See the build history.

I noticed that they save some extra info in their files. And they have increased the precision of stored numbers.

In this MR I take into account these changes, when testing VTK recorders.
