[1975] use EXPECT_TRUE with == inside it, instead of EXPECT_EQ to make it build.

Since no operator<< for SearchResult is defined, EXPECT_EQ doesn't compile,
at least not on some environment.  This is not the only way to fix it, but
reviewing it without having buildable tree is quite difficult, so I'm
tentatively making the easiest fix and committing it.  Feel free to override
it.
