Ruby: Use `Array(thing)` instead of `thing || []`

I learned something recently. Our code used to be peppered with this:

result = something.else || []

Or variations on the theme:

a_string = (something.else || []).join(',')

Turns out you can just

result = Array(something.else)
a_string = Array(something.else).join(',')

Minor convenience, but lovely nonetheless.
