Speculatively exclude SmartSessionRestoreMRUTest.CorrectLoadingOrder on DrMemory.
Even though SmartSessionRestoreMRUTest.PRE_CorrectLoadingOrder is excluded, it's
still running, and I'm theorizing that it's because exclusions don't work well
for PRE tests.
This started turning the bot red in
http://build.chromium.org/p/chromium.memory.fyi/builders/Windows%20Browser%20%28DrMemory%20full%29%20%285%29/builds/3805,
but it was failing and yellow before then.
