Bugfix: Autokeying was non-functional after the Keying Sets refactor

- The RNA wrapping for the generate callback was still wrong, with the primary effect being that C-code calling this had unexpected consequences that were hard to debug.
- Fixed some defective checks that meant that when specifying the RNA-pointers for the Keying Set to use (rather than using the Keying Set's own iterator callback) would never add any info.
