* Attempt to write a new test for cert update
Trying to surface this bug with a test:
https://github.com/hashicorp/terraform/issues/5930
* Fix the error
* Fix the test for the update operation
* Break apart tests for EU vs US to cleanse test run
* Refactor Update to more closely match create, increase debug logging
* Reflect differences of EU and US regions via separate tests
* Add comment re: why of test breakout
* Removed the “SetId” as it was unnecessary
* Ensure the SSL Addon has been provisioned
* Randomize app name in test
* Return error and don't panic when there is a problem
It's possible there may still be an underlying problem that caused the
error that made the cert leak in the first place - this should help us
diagnose it.
