BUG: Explorer plugin navigate path should only show results in current path

[jjw24]

Currently when navigating paths e.g. c:\blah it shows results from Quick Access Links as well.

Reproduce:

1. Add c:\blah\myBlah\blahFile to Quick Access Link
2. Enable Path search
3. Navigate to c:\blah\, c:\blah\myBlah\blahFile should not be shown.
   Not sure if blahFile is coming from Quick Access Link or Path Search (worth checking and making sure).
