RangeError when deleting a process

Sentry Issue: ARKINDEX-FRONTEND-AGZ

RangeError: invalid date
  at call (./vue/Process/Row.vue?56c1:1:912)

It seems the date parsing that shows an ISO 8601 string in the title attribute can get a bad date when the process is being deleted. Probably a race condition or something alike in Vue's component rendering; this just needs a null check.
