- 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

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
