[JavaScript] Invalid definition classes

Description

Entities specified as swagger definitions are imported with Definitions prefix,

Swagger-codegen version

Docker image with swagger-codegen-cli 2.4.2

Swagger declaration file content or url

For example, given the next declaration:

{
  ...
  "definitions": {
    "Company": {
      "type": "object",
      "properties": {
        "uid": {
          "type": "string"
        },
        "name": {
          "type": "string"
        },
        "companySize": {
          "$ref": "#definitions/CompanySize"
        }
    },
   "CompanySize": {
      "type": "string",
      "enum": [
        "small",
        "medium",
        "large"
      ]
    },

next files are generated: model/Company.js and model/CompanySize.js but the problem is the model/Company.js has de code:

import DefinitionsCompanySize from './DefinitionsCompanySize';

which should be

import CompanySize from './CompanySize';

Command line used for generation

docker run --rm -v ${PWD}:/local swaggerapi/swagger-codegen-cli generate -i /local/swagger.json -l javascript -o /local/api-sdk --additional-properties usePromises=true,useES6=true

Reproduce the generated model files with the reported Docker command and declaration, then inspect the JavaScript generator templates that produce imports for model/Company.js and model/CompanySize.js. The work is done when Company.js imports CompanySize from './CompanySize' rather than DefinitionsCompanySize from './DefinitionsCompanySize'.
