wsod screen not rendered when handled error thrown during rendering

[janmisek]

Reproduce:

• throw any error in computed of component rendered by route
• wsod rendering fails on same error as handled (ember probably tries to re-render failed view)

Reproducible by test: https://github.com/janmisek/ember-error-handler/blob/master/tests/integration/wsod-consumer/rendering-after-error-is-possbile-test.js

Much better reproduction case is available:

Bug to be submitted:

• throw any error in computed of component
• handle error in some global handler
• redirect to another page which should show error
