Fix DND property to calendar aggregation function

[travisstebbins]

Summary

This PR fixes a bug where users are unable to DND a property from the explorer panel to a calendar aggregation function. The bug was introduced here (https://github.com/finos/legend-studio/pull/3185) because allowing the user to DND to the entire fetch structure panel blocked DND onto a calendar aggregation function.
