This is used to display and verify output of "Path -&gt; Alias" in test framework.

QTestUtil masks "Path -&gt; Alias" and makes verification impossible.
By keeping "Path -&gt; Alias" intact and adding a new display name which is not
masked by QTestUtil by removing prefix.

Notes: we would still be masking for intermediate directories.
