Consider back documenting to enzyme's open issue

[k2snowman69]

From what I gather (still processing, apologizes if my understanding is incorrect) this seems to be a stop-gap measure until React supports Enzyme with some sort of event regarding effect callbacks which is effectively tracked via enzymejs/enzyme#2086.

However the documentation for this package doesn't reference this issue which I think would be useful for additional context if people are interested... or if the issue does ever actually get resolved, as a back reference to what the official solution ends up being.

Just something to consider, thanks!
