Fix test_property_graph_mg Usage of Util Function (#4600)

This PR fixes an issue that recently arose due to a change in constructing a `cudf.Series` object.

`test_property_graph_mg.py` uses a function from `utilities/utils.py` to construct a Series object from 2d arrays. The function is now using the correct `cudf.Series._from_column` API.
