#14345 Refresh the owning object when data filters are added or removed

The data filter collection node is hidden in the project tree while the
collection is empty, and the owner must be refreshed to re-run its tree
ordering when the first filter appears. The refresh targeted the source
case, which for a grid ensemble collection is the main case of the
ensemble, not the ensemble owning the tree node. Newly created ensemble
data filters were therefore not visible in the tree.

Refresh the PDM parent object instead, which is the case or the grid
ensemble. Also refresh from the programmatic removeFilter path.
