Bug Fixes
- **paraview**: Remove unnecessary check for import
([`301b684`](https://github.com/Kitware/trame-vtk/commit/301b684378f30d46e93939da67ebd11f2027bf41))
It is okay to check the servermanager import at the time of instantiating the Helper class, and we
do not need to check for the servermanager when the module is imported.
