read last line of ignore file (#1155)

* read last line of ignore file

- do not cancel other matrix jobs if one test fails
- read all lines of the ignore list even if it doesn't end with a newline
- add ignore list for 0008 and 0009

* support missing object numbers when brute-forcing

the file 10404 (ironically) contains not found references with number 43 0
for its info dictionary. changes brute-force code so that objects can be
entirely missing

* fix test since document is now opened successfully but mediabox is broken
