Do we have any tests in this area?

I'll see what I can find. Even if we did, unless the test explicitly asserted the value of the field we probably wouldn't have noticed: since AssemblyResolve stops calling further handlers after one gives a successful resolution, the extra ones just aren't called. So this is really only a memory leak given we might subscribe n times instead of 1 time, but the n is somewhat bounded by the number of analyzers loaded in the process.

This is a port of dotnet/roslyn#53166. There's a bigger question here about how to reuse this code better, but this caused a bunch of confusion while debugging an issue.
