Closes #39 Adds a test or the scenario described in issue #39.

I took the opportunity to add a minimal test harness based on tape.

Hi @hgwood :)
Thanks for submitting this PR, we appreciate any kind of desire to help. Before merging this PR could you notice that the latest version of this TodoMVC is under the branch onionify. We should merge it to master soon, when onionify v4 is launched. Could you make this PR against that branch? I'm not even sure if the bug would still occur in the branch.

Hello @staltz (should have said that first, sorry). Thank you for your kind reply and pointers. After a quick look at the code, it seems the bug is indeed fixed in the onionify branch. I will confirm by rebasing and running the test later. Would you still be interested in merging the test into onionify?

[hgwood]

I have changed the test to match the new app. It does show the bug is fixed.

Hi @hgwood, thanks for the interesting test to keep this bug from returning. (I'm going through dozens of issues and PRs)

I would merge this, but as a single isolated test it may feel odd to someone browsing the source code when learning this. So I'll leave this PR open, you can choose whether to close it or add more comprehensive tests so that the whole codebase is tested.

[hgwood]

I understand. I will close it in favor of other priorities. Thank you for your consideration.
