Bug 1560329: We were neglecting to rewire the "cancel/remove"
button on a block config after a Pieforms validation failure.
A pieforms validation failure (when you're using Pieforms'
jsforms feature) actually replaces the current form with a
new one, rather than just inserting error messages into the
existing form.
