Fixes a runtime error being thrown by Angular when opening multiple snack bars, that have a timeout, in quick succession. The fix waits for the zone to settle before firing the final callbacks.
Note on testing: This change is missing a unit test, because I couldn't find a way to trigger the error during tests, however the approach is similar to #2219.
Fixes #2390.
