Update rspec 2.13.0 -> 2.14.1

After updating rspec, I noticed some deprecation warnings about `stub`,
instructing me to use `double` instead. So, I made that change at this
time to help things be ready for the future.

At the same time, I converted some double quotes to singles for code
consistency, and aligned some `let` blocks on the curlies for
readability.
