Merge #12810: [Tests] Fix a typo at assert_start_raises_init_error() and use specific exception for initialization error

8394300859 [Tests] fix a typo in TestNode.assert_start_raises_init_error() (Roman Zeyde)

Pull request description:

  `self.wait_util_stopped()` should be `self.wait_until_stopped()`.

  Also, use a specific Exception subclass for indicating node failure to start (instead of using `AssetionError` and an `except Exception` clause).

  Following https://travis-ci.org/bitcoin/bitcoin/jobs/359066226#L2726 and depending on #12806 (which fixes the root cause of the Travis test failure).
