Exception after destroying submission

[damianhxy]

Your environment
Carnegie Mellon's Autolab

Steps To Reproduce
Reported but unable to reproduce. Manifests after destroying a submission. Does not persist to future page loads.

Seems to have to do with @submissions still containing the destroyed submission when index is loaded.

Hypothesis: submission is reported as destroyed but is removed from the database between definition of @submissions and rendering of template.

Stacktrace

An ActionView::Template::Error occurred in submissions#index:

Couldn't find Submission with 'id'=8972176
