Use isset() instead of array_key_exists() in DIC

Use isset() instead of array_key_exists() in DIC

It doesn't look like the array_key_exists() in Container::get() and Container::has() is necessary. Changing this to isset() removed over 1,000 calls on a default Drupal 8 install - attaching before/after xhprof screenshots with this change.

Button missing getErrorsAsString() fixes #8084 Debug: Not calling undefined method anymore. If the form contained a submit button the call would fail and the debug of the form wasn't possible. Now it will work in all cases. This fixes #8084
