When renaming a folder, the refactoring fails with the following exception:

Steps to reproduce:

# create a project with one folder 'sources'
# create a source model 's1' in that folder
# create a view model 'v1' in the root of the project, transform from s1
# do Refactor > Rename on the *folder*
# the Rename Resource dialog shows an error message "A fatal error occurred while performing the refactoring", "Overlapping text edits" (see screenshot)
