cril (introduce let) does not properly indent the body of the new let form

[daveyarwood]

For example, I have this top-level form:

(defrpc campaigns
  [& [opts]]
  {:rpc/pre (and (have-api-key) (have-network))}
  (->> (view/campaigns (network) opts)
       (map #(safe-parse-json % :customfields))))

When I put my cursor on the ( before ->> and enter cril and enter cs for the binding name, the result is:

(defrpc campaigns
  [& [opts]]
  {:rpc/pre (and (have-api-key) (have-network))}
  (let [cs (->> (view/campaigns (network) opts))]
       (map #(safe-parse-json % :customfields))))
cs

I use parinfer, so it re-balanced my parens because cs was all the way to the left, so it was judged to be another top-level form. The bindings part of the let also got closed prematurely because the line after it wasn't indented far enough to the right.

If I disable parinfer and do the same thing, I get this, which is still not indented properly:

(defrpc campaigns
  [& [opts]]
  {:rpc/pre (and (have-api-key) (have-network))}
  (let [cs (->> (view/campaigns (network) opts)
       (map #(safe-parse-json % :customfields)))]
cs))

Note that not only is cs not indented at all, the previous line also has incorrect indentation now because it didn't move from where it was before.
