[Bug] Renaming folders: changes are not applied

Actual behaviour

It's not possible to rename a folder if only the capitalization of the letters is changed. F.e. renaming "Abc" to "abc" has no effect. No error appears, but the name simply stays "Abc".

Expected behaviour

It should be possible to rename a folder even if only the capitalization of the letters is changed.

User benefit

It's not an unusual thing to misspell a word only by accidentally typing in a lower case letter instead of an upper case letter. It should be possible to rename files in any case, including this situation. Currently, the user is forced to take an indirect way of firstly renaming the file to another wrong name and then go back to the old name, this time capitalized correctly.
