**Describe the bug**
When using the search bar to search for nodes with a particular property on a particular node type, properties with datetime values don't appear. For example in the below, `Transaction` nodes have two properties, `Amount` and `Created` - but only `Amount` shows up as a possible property to filter on.

Searching via the connections pane does show the property though, as seen below:

- OS: Amazon Linux 2
- Browser: Firefox
- Graph Explorer Version: 1.1.0
- Graph Database & Version: Amazon Neptune 1.2.0.2

**To Reproduce**
Steps to reproduce the behavior:
1. Load the sample fraud data set via %seed
2. Use the search bar to filter the search to nodes of type `Transaction`

**Expected behavior**
Ability to search for nodes via search bar on its datetime property value.
