Bug: Deletion of selected workflow executions does not update selection count

[ChrisHuynh333]

Summary

Currently on the Workflow Execution Tables (user and projects), if a workflow that's selected is deleted (from both index and show), the selection is still stored in LocalStorage.

Acceptance Criteria

Rather than using turbo-delete to handle deletion confirmation, create a DeletionsController to handle the confirmation dialog and destroy action, as well as handling updating LocalStorage upon delete confirmation.

This logic is already used in multiple areas of IRIDA Next which can be referenced (samples, metadata, attachments).
