I edited package.el as per the diff of that commit and eval'd the changed
function.

I can still recreate the problem. Here's what I did:
1. Uninstall git-timemachine using package manager.
2. See that the custom.el is updated (git-timemachine getting removed from
package-selected-packages)
3. Re-install git-timemachine
4. Now the package-selected-packages var gets updated but does not get
written to custom.el automatically.

I believe this issue has been here for a while but I didn't get to chasing
it; doesn't have to do with async install feature revert. It's just that
now it matters more since we have the package-autoremove function.
