Fix page-ref rule which was not bindable and failed fast

- page-ref had a :block/name embedded lookup ref which failed fast.
  datomic advises against this -
  https://docs.datomic.com/on-prem/schema/identity.html#:~:text=You%20cannot%20use%20them%20in%20the%20body%20of%20a%20query%2C%20use%20datalog%20clauses%20instead
- page-ref can handle binding args like last commit for page
- page-ref not failing fast on non-existing pages means that user can get meaningful results
  in more complex queries as seen in test
- Also remove try/catch as there should be no more queries that
  unintentionally cause the 'Nothing found for entity' error
- Also fixed lookup ref in srs cards which can be seen in stacktrace of
  #4576
