Denied authorization for READ_HISTORY on proc_def leads to error on dashboard

• given:
  • Engine and Optimize are up, configured and running
  • I am an admin user and created a report for "invoice" process and place it on a dashboard.
  • I give user john permission for "READ_HISTORY" for all process definitions, but not for "invoice" process.
• when:
  • I log-in with user john
  • I try to open the dashboard that admin has created with the report of which I am not allowed to see the content

• then:
  • Optimize front crashes and I see "Cannot read property view of undefined"

• expected:
  • john should be able to see the dashboard, but not the report / data of the report

Hints: Also the whole report disappears from the report list for john.
