Cannot delete folders from raw repositories if they contain spaces

Create a folder with a space in the name in a raw repository:

curl -u admin:admin123 --upload-file a.zip "http://localhost:8081/repository/raw_repository/A%20Space/some/path/a.zip"

Then go to the browse tree UI and attempt to delete the folder. You'll get a message saying that the folder is being deleted in the background. But it is never deleted. The log shows no failure, even with ROOT logger at TRACE level.

Expected: Deletion of a folder with spaces in it should succeed. All deletion attempts should be logged at INFO level. If something goes wrong, it should be logged at ERROR level.

Workaround: Delete the files within the folder hierarchy one at a time, and the folders will be cleaned up once they are empty.
