Re: The Amazing Self Replicating Configuration of Developer Toolkit

I suggest adding the review check anyway--it is a subtle issue.

Subject: [nvda-addons] The Amazing Self Replicating Configuration of
Developer Toolkit

I am curious if anyone can replicate (no pun intended) this issue.

I've been doing some development, and reloading add-ons frequently.
I happened to notice on one such occasion, that I had two NVDA configuration
settings entries for Developer toolkit: one near the bottom of the list, and
one toward the second third.

For fun, I reloaded add-ons several more times, and what do you know: for
each one, another "Developer Toolkit" appeared on the list. I reloaded NVDA
entirely and tried again, with the same effect, although it did at least
start over at one.
I think I had it up to seven occurrences before the novelty lost its charm.

NVDA beta-18270
Latest stable developer toolkit.
Windows 10, 1903, 64bit.

I can provide logs, but there doesn't seem to be anything unusual there.
