Java imports code action breaks namespace form

[Artem Medeu]

Describe the bug
In some cases import java package code action breaks :import section of a ns form. I believe it happens when a new package's path matches to one which already imported. E.g. java.awt.event and java.awt.<something>.

To Reproduce
Steps to reproduce the behavior:

1. assume following ns declaration:

(ns my.namespace
  (:import [java.awt.event ActionEvent]))
  
;; ActionEvent is used somewhere in the code

2. Add a new java class usage Robot.

(def robot (Robot.))

3. Execute code action which suggests to add java.awt.Robot to imports declaration
4. Form becomes broken:

(ns my.namespace
  (:import [[java.awt Robot event] ActionEvent]))

Expected behavior
A form should look like this:

(ns my.namespace
  (:import [java.awt.event ActionEvent]
           [java.awt Robot]))
