After looking into this further, I learned that reinstalling packages adds
code in *-autoloads.el file to set load-path.

So my problem was resolved by reinstalling all my private ELPA packages.

As far as I'm concerned, this is no longer a bug.
However it looks like recent change in package.el requires everyone to
reinstall all their packages!
