DumpRenderTree should reset its preferences file on launch

DRT has a function resetDefaultsToConsistentValues() which is supposed to set
the defaults to exactly how we want them for testing.

If you happen to have a default set from a previous run of DRT which you no
longer want set it will not remove that default.  It should.

This is what was causing the commit-bot failures landing bug 29612.  My fix for
bug 28624 which disables Hardware compositing was sticking in DRT's preferences
and not getting reset, even though that change has not landed yet.  I had
expected that DRT started from a clean slate of preferences every time, but it
does not.
