System.ObjectDisposedException: Cannot access a disposed object

[MattMofDoom]

Hi @AntoineGa @nblumhardt ,

After the changes in #19, v2.0.37 throws a System.ObjectDisposedException.

I've reverted to v2.0.0 and haven't looked too deeply,, but it looks like _httpClientHandler is somehow being disposed, possibly after the first successful post.

Export of the error attached for your convenience, with the webhook attributes masked.

Sorry, I introduced this one when lifting HttpClientHandler construction into OnAttached(). #24 should sort this out 😓

the fix is on 2.0.38
