Run BrowserThreadTest.RunsTasksOnCurrentThreadDuringShutdown on UI thread.

In preparation for the migration of the FILE thread to TaskScheduler,
we want to disable destruction observers on it.
BrowserThreadTest.RunsTasksOnCurrentThreadDuringShutdown is the only
test that fails when destruction observers are disabled on the FILE
thread. This CL changes this test to use the UI thread instead.
