fix: delete symlink itself instead of referenced directory

[amedama41]

Issue

delete action for a symbolic link referenceing directory deletes the directory instead of the link itself.

Cause

The path used by delete action has '/' suffix, then the target is not the symbolic link itself.

Change

Remove '/' suffix from the path when deleting a symbolic link referencing directory.
