`clojure-align` misaligns code that is improperly indented

[kylc]

Expected behavior

Using clojure-align on a block like this, which is not properly indented to
begin with:

(let [a-long-name 10
b 20])

Should result in properly indented and aligned code, like this:

(let [a-long-name 10
      b           20])

Actual behavior

A single clojure-align application results in this:

(let [a-long-name 10
      b                 20])

A second application arrives at the proper result.

This is due to the clojure-align implementation, which first aligns the region as-is, then performs an indentation step.

Steps to reproduce the problem

Use clojure-align on improperly indented blocks of code, as above.
