`cljr-sort-project-dependencies` drop :dependencies section when using managed-dependencies

## Expected behavior

When using `:managed-dependencies` in a leiningen project, the `:dependencies` section is dropped
while using `cljr-sort-project-dependencies` instead of being sorted

## Steps to reproduce the problem

Assuming this `project.clj` file:

```clojure
(defproject superfun/happyslide "1.0.0-SNAPSHOT"
:description "A Clojure project with managed dependencies"
:min-lein-version "2.7.0"
:managed-dependencies [[clj-time "0.12.0"]
[me.raynes/fs "1.4.6"]
[ring/ring-codec "1.0.1"]]
:dependencies [[clj-time]
[me.raynes/fs]])
```

After: `M-x cljr-sort-project-dependencies`

Buffer is updated as follow:

```clojure
(defproject superfun/happyslide "1.0.0-SNAPSHOT"
:description "A Clojure project with managed dependencies"
:min-lein-version "2.7.0"
:managed-dependencies [[clj-time "0.12.0"]
[me.raynes/fs "1.4.6"]
[ring/ring-codec "1.0.1"]]
:dependencies )
```
