Sending the defined `defaultValue` in `oh-input` widget does nothing without "touching" the value

[boehan]

The problem

If a defaultValue is defined for a oh-input widget, the value can not directly be sent by clicking the send button (does nothing). The value has to be edited once before the the value is actually sent (can even be set back to defaultValue before sending).

Expected behavior

Should be possible to directly send the defaultValue to the item. Otherwise setting a default doesn't have much purpose.

Steps to reproduce

1. Create an oh-input widget
2. set an item (which should have a NULL state) and a defaultValue for the widget
3. enable "Send button"
4. Use the widget and directly click the send button to send the default value to the item

Sample widget code:

component: oh-input-card
config:
  defaultValue: TestDefault
  item: TestItem
  title: DefaultValue Tester
  outline: true
  sendButton: true
  type: TEXT
