Investigate publish error with v1.0.0-rc2 and Pogly's C# module

[cloutiertyler]

@RReverser looks like there's a bug on the release/v1.0.0-rc2 branch. I can help you reproduce. It could be an issue with my cherry-picking, but either way let's work on a fix first thing Monday.

To reproduce publish https://github.com/PoglyApp/pogly-standalone/tree/1.0.0-rewrite/server using #2052

Let's add a new regression test for this one as well once we figure it out. It didn't get caught in our automated testing

From a quick glance, it looks like the issue that was fixed by #1987.

The publishing in this case invokes some irrelevant reducer instead of "init" one, and then fails due to argument mismatch. It is similar to the bug I fixed there, with wrong reducers being called.

Can you confirm if that PR was included in the release? It seems like it should be since I made it over a month ago, but just in case.

I checked, publish works on master SpacetimeDB, so it's very likely either that PR or something else that was already fixed.
