This test doesn't work as this test fixture can't initialize a Crashpad
reporter, I'll try to find how to fix this.

+  EXPECT_NE(nullptr, reporter);
+  asan_ReinitializeCrashHandler();
+  EXPECT_NE(nullptr, asan_runtime_.crash_reporter());
+  EXPECT_NE(reporter, asan_runtime_.crash_reporter());
+}
