[BUGFIX] Do not abort renameFile if filename sanitizable

It is possible to rename a file with ResourseStorage::renameFile(). This
is also used under the hood, if a file is renamed in the file list.

RenameFile also performs a sanitation of the filename, in case the
filename was not yet sanitized (e.g. convert chars like space, quote,
ö, ê, ß or §).

But if the target filename is the same as the current filename, the
sanitation was not performed. This is now fixed so that the behaviour
is more consistent and sanitizing files with renameFile() is possible.
