test: serialization_test_properties: fix stale stack use

Fix use of stale stack variable.  The previous code saved
the result of `path.filename().c_str()`, but since the results
of filename are a temporary it and its `c_str` only exist for
the lifetime of the statement and thus cannot be saved.

Make minor modification to the function to save the `filename()`
portion of the path rather than the filename's `c_str`, thus
extending the lifetime of the `filename()` return.
