Save encrypted files without IDs in CPDFSecurityHandlerEmbedderTests.

Add methods to CPDF_Parser and CPDF_CrossRefTable to strip the /ID entry
from the PDF trailer. Use this in CPDFSecurityHandlerEmbedderTests to
exercise the PDF creation code paths where they attempt to write out new
encryption dictionaries. This uncovered at least 2 bugs in the code, so
some of the new test code is disabled for now, with TODOs to fix them.
