JDK-8217777 TEST_BUG: jdk/java/util/prefs/ExportSubtree.java passes even when test should fail

[Roger Riggs]

Hi Steve,

Add 8217777 to the @bug line; it helps track and run tests that fixed 
bugs  (jtreg -bug:8217777)

+1 printing the expected and actual (when a failure occurs).

Looks fine overall.

Thanks, Roger
