Default value selected on change for Object destination on Relation field

[vlad610]

Bug Description

This is a minor issue with the user interface. When you create a Relation field on an object, when you select the "Object destination", after de-selecting the preselected object (e.g. Companies), when you select a new object, the initial one is also selected, and "2 Objects" is shown.

Steps to reproduce:

1. From Data Model in Settings, add a new Relation field on an object.
2. Notice "Company" is pre-selected under "Object destination"
3. Expand the drop-down, de-select the default object and select a different object (e.g. Opportunity)
4. Notice both values are selected (the initial one is selected again).

Expected behavior

Only the one option you select should be selected, not two.

Workaround

Remove the initial default selection after it's re-added.
