I could not see a meaningful reason behind calling `forbid` so early in
the settings initialization block. But moving the `forbid` call until
later resolved this issue.
In the real world, I don't see how this would cause issues. But I found
that calling `forbid` when `wiki_options[:allow_editing]` was set to
false caused order-dependent test errors where Sprockets would end up
being badly configured and left without an initialized
`Sprockets::Environment` object, which is required by the
`sprockets-helpers` gem to resolve asset paths.
The test that would cause errors is also in this commit diff. I've
updated it to be a bit more readable.
I also took this opportunity to review and clean up the `@allow_editing`
assignment, which seemed a bit obfuscated.
