Get rid of `realMatchPlugin`

I didn't even need the `matchPlugin` that took `plugins` as an argument,
I can just use the `plugins` function directly in `matchPlugin`. Get rid
of `realMatchPlugin` because that was just a temporary name until I got
things working.

Move `firstPlugin` into the definition of `matchPlugin` because it's not
needed anywhere else and is just used to pattern match for the first
matched plugin in the list.
