Typing in an Edge Source/Target node name does not enable the "Save" button

The Problem

The AutoComplete field is designed to support a variety of input methods, including selecting by clicking on the graph and typing a partial name, viewing suggestions, and selecting a suggestion. This generally works well when it's used in the Search field or the NodeSelector form.

When editing an edge, the AutoComplete field is also used to set the Source (and more commonly) the Target nodes. This generally works well when the user either clicks on a node on the graph to select it, or when using type-ahead to select a node -- they type a partial node name, then they click on the full name in the suggestion. This works because clicking on a suggested node triggers a SOURCE_SELECT event, where we can verify that the selected node is a valid node.

The problem occurs when the user types in the full name of the node and then hits Tab to go on to the next field. In this case, no event is triggered, so we never verify that the node name typed in is a valid node, and therefore we don't re-enable the "Save" button.

To replicate:

1. Select a node
2. Click "Add New Edge"
3. Type the name of another edge and hit "tab"
4. The "Save" button remains disabled because the system doesn't know we have selected a valid target node.

The simple solution might be to use an unfocus event on the AutoComplete field to trigger a selection verification.
