[gcc] Fix compiler warning turned into errors with gcc while compiling extension_sync_data_unittest.cc

With gcc toolchain, we get following error with EXPECT_FALSE

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

Changing EXPECT_EQ(...) to EXPECT_FALSE() fixes the error.
