Add `reload!` to irb after adding `tag_list` method.

We were already working in the rails console a few lines up and then the tutorial has us change our model and then we jump back into the rails console.

If you don't have the 'm' to go with the '-a' flag you will get this error: "fatal: Paths with -a does not make sense".
