can't use functionName in template function file

[zamirdan]

Hi,

this variable is only available in the "template for a test file".
it's a simple fix that could really help us.
Thanks,
Dan

createAWSNodeJSFuncFile(handlerPath) {

const functionName = this.options.f || this.options.function;

const handlerInfo = path.parse(handlerPath);
const handlerDir = path.join(this.serverless.config.servicePath, handlerInfo.dir);
const handlerFile = `${handlerInfo.name}.js`;
const handlerFunction = handlerInfo.ext.replace(/^\./, '');
let templateFile = path.join(__dirname, functionTemplateFile);

if (this.serverless.service.custom &&
  this.serverless.service.custom['serverless-mocha-plugin'] &&
  this.serverless.service.custom['serverless-mocha-plugin'].functionTemplate) {
  templateFile = path.join(this.serverless.config.servicePath,
    this.serverless.service.custom['serverless-mocha-plugin'].functionTemplate);
}

const templateText = fse.readFileSync(templateFile).toString();
const jsFile = ejs.render(templateText, {

handlerFunction,
functionName

});

const filePath = path.join(handlerDir, handlerFile);

this.serverless.utils.writeFileDir(filePath);
if (this.serverless.utils.fileExistsSync(filePath)) {
  const errorMessage = [
    `File "${filePath}" already exists. Cannot create function.`,
  ].join('');
  throw new this.serverless.classes.Error(errorMessage);
}
fse.writeFileSync(path.join(handlerDir, handlerFile), jsFile);

this.serverless.cli.log(`Created function file "${path.join(handlerDir, handlerFile)}"`);
return BbPromise.resolve();
