Multiple playlist with the same name is allowed

Description
If we use the name of an existing playlist to create a new playlist, the original playlist gets cleared because it is overwritten.
We shouldn't allow creating a new playlist if the name already exists.
According to Allan Day, we should just select the row for the original playlist if it already exists.
