[BUG] Cannot transform meta field value when field is already fetched before.

[Levdbas]

Expected Behavior

     $this->meta('related_project');
      $projects = $this->meta('related_project', [
         'transform_value' => true,
      ]);

// Projects is still now an array instead of id's

Actual behavior

When a field value is already fetched it will not transform anymore.

Steps to reproduce behavior

1. Create ACF date field & add it to a post
2. Get post value by

$date = $this->meta('start_date', [
   'transform_value' => true
]);

3. See that the field is transformed,
4. Now add $date = $this->meta('start_date) before that line
5. See that the value does not transform anymore.

Notes

Not sure if we want to fix this, but we must at least document this behaviour if we are not going to change it.
