Phriction Action View won't render weird actions when document does not exist

Summary:
The actions wouldn't behave as I want. Disabled them and display "Create Document" instead, since the others make no sense on a non-existing page.

The linking was error-prone btw. `/phriction/edit//` (how it and others would be linked) wouldn't route to anything, and even if, would result in an error anyway since non-existing docs can't be deleted nor have their history shown.

Test Plan:
verified buttons disappeard…
