Fix drag and drop error in Playwright

[TomasEng]

Description

Updated the dragComponentIntoDroppableList method so that it doesn't matter whether the list is empty or not. I have also tried to clean up the code a bit, with a dragAndDropManually method on the BasePage class. This method should be used in favor of Playwright's dragTo method when we don't now exactly which element that will receive the drop event. In this case it may be either the list element or some unknown list item element, depending on whether the list is empty or not.

Verification

• Your code builds clean without any errors or warnings
• Manual testing done (required)
