Selected value disappears when clicking outside datepicker and using internal-model-change

[laurens94]

Describe the bug
Since version 8.4.0 the selected value disappears whenever I click outside the modal.

To Reproduce
This only seems to happen when using the @internal-model-change event.

1. Go to https://stackblitz.com/edit/vuepic-vue-datepicker-1huhba?file=src%2Fcomponents%2FPlayground.vue
2. Click on the datepicker
3. Select a date
4. Open the datepicker again
5. Click outside the picker modal
6. See how the selected value disappears

Expected behavior
I expect the same behavior as when @internal-model-change is not being used.
