Bug 1708235 - Remove broken console-instant-eval test r=evilpie

This test was added in Bug 1651420, and then broken silently, due to an error
in the activation of the test by Bug 1653567. This edge case behaviour
shouldn't block us from landing private fields and methods

Tracking fixing this I have opened Bug 1708812.
