On case-insensitive filesystems, the copy+unlink fallback shouldn't be attempted since source/destination can "overlap". Also adds some additional logging for error conditions + one at debug level for a more common scenario. Otherwise just some additional tidying for readability.

Maybe also rename this variable $targetParent

Even if it's current behaviour, I am not sure we need to remove the target when it's a file.
It should be overwritten by the rename. Not sure if it's dependant from filesystem…

Summary
During rename operations, if something already exists in the destination path, it gets deleted prior to the forbidden items check. If the check doesn't pass, the operation is aborted but deletion has already occurred.
This PR moves the forbidden items check up so it takes place before any destructive activities occur (see
checkTreeForForbiddenItems).The 2nd commit also addresses an edge case where the copy+unlink fallback could still be triggered for case-only renames on case-insensitive filesystems.
