Make an unmodifiable copy of the list with current file paths

The list with the current file paths that is stored in ChangeData
should not be modified. To protect against modifications it is made
unmodifiable and when setting the list a defensive copy of the passed
list is done so that changes to the passed list after the fact do not
impact the list stored in ChangeData.
