Undo "rebundle" commit

### WHAT

Undo the code changes from this commit from 8 months ago: https://github.com/binarylogic/authlogic/commit/00b921e24fd38c4241efe2d270c64527d1bb204f

### WHY

I just came across this commit, and noticed it reverted a couple recent changes. The title indicates it was probably only to update the `Gemfile.lock` file.

All the changes that were reversed seemed good, although there was one with an unanswered question on  it (https://github.com/binarylogic/authlogic/commit/8bcdb3bd5ab7d0ff6ec92349ae09324b4ce4d778).
