BibIndex: journal page tokenizer
BibUpload: factor out step 6

* Move out the job end dates updating in a separate function
  to be able to call it in tests.
BibIndex: test concurrent bibupload and bibindex
BibIndex: do not use hstRECORD

* Disables the filtering step that uses `hstRECORD` table:
  set always `force_all_indexes=True` when calling
  `find_affected_records_for_index`

* Fixes `find_affected_records_for_index` when called with `recIDs=[]`

* Fixes two regression tests
