Use EXPECT_FALSE instead of EXPECT_EQ for comparing false

Use EXPECT_FALSE instead of EXPECT_EQ for comparing false

Using EXPECT_EQ(false, condition_expr) assertion gets the following error with gcc 4.8.x toolchain on linux
when building unit test:

error: converting ‘false’ to pointer type for argument 1 of ‘char testing::
internal::IsNullLiteralHelper(testing::internal::Secret*)’ [-Werror=conversion-null]

It is a mysterious problem occurred in gtest. Only EXPECT_EQ(false, condition_expr) cause the compile error, while EXPECT_EQ(true, condition_expr) can work well.
