Blank line under empty subdir

SUMMARY
When a session has a directory that has only a subdirectory, and the subdirectory has no files, the file browser adds a blank line under the subdirectory. It persists even after files are added.

STEPS TO REPRODUCE
1. Create the following directory structure:
project/parent/subdir
2. In a new Kate session, open the "project" folder
3. Display the file browser on the left if necessary

OBSERVED RESULT
There is a blank line with a line next to it, as if there was a file, but where the filename would be there is a blank space

EXPECTED RESULT
There is nothing shown under the subdir directory
