[typescript-angular] Missing import

[jeanbisutti]

Description

Bug: missing import in the generated Typescript service

Swagger-codegen version

Bug reproduced at versions 2.4.9 and 3.0.33

Swagger declaration file content or url

JSON available here

Command line used for generation

java -jar swagger-codegen-cli-3.0.33.jar generate -i "model.json" -o "generated" -l typescript-angular

Steps to reproduce

Execute the command line above with this model.json

The generated api/userMapReturnController.service file needs an additional import to compile:
