Subject: [PATCH] accesslib: remove references to deprecated context_rel table
 and insert_context_rel()

These references to the deprecated functions were erroring out. Remove
them.

Note however that other role related cleanups done as part of
MDL-10679 "improvement to context_rel table and load_user_capability()"
are kept.
