Coverity was complaining that we don't check the return value, which we stopped doing in772e0a76f3. But it seems that we don't want those calls at all. The test was originally added with the call ina6ee01caf3, but I don't see why we should override this. If the user wants to execute the test with mempool disabled, we shouldn't ignore that. Coverity CID#1444464, CID#1444466.
