[console - webhook] TEST button times out when using custom Response Topic

[JelmerT]

Bugs

TEST button in webhook config times out when using custom Response Topic, even though a 200 HTTP/OK is received from server.

Expected behavior

Test button should display a green box with 'webhook working, got 200 from server'

Observed behavior

Orange box with Timeout

Steps to reproduce

add a custom Response Topic and test the webhook with the button

The test button can be improved a lot (also see #61 and https://community.particle.io/t/webhook-test-button-and-json-value-in-particle-event-value/50602)

If choosing not to improve it, I vote to remove it, since it's very confusing and not actually helping debug the webhook.
