CompatabilityTest failure when adding a new element

[wahoho]

I wanted to create a PR for the "template" element. Followed the steps here https://github.com/Kotlin/kotlinx.html/wiki/Development but when I ran the test, it keeps failing because of CompatabilityTest (mismatching declarations.json). I checked that the jvm/src/test/resources/declarations.json were commited by Sergey Mashkov.

Since it wasn't in the wiki, I was wondering how to fix/bypass this test since this looks like a file I shouldn't be touching.
