Download base images doesn't work only with prepareBaseImage global

[caragpe]

When using method _assertVisualDiff , we are only downloading the base image if the options param explicitly includes the option {prepareBaseImage: false}. Otherwise, it will omit downloading the base file, even if the helper configuration includes the prepareBaseImage option.

My suggestion is to check the config option for prepareBaseImage when this option is missing in the _assertVisualDiff method:

const prepareBaseImage = options.prepareBaseImage !== undefined
      ? options.prepareBaseImage
      : (this.prepareBaseImage === true)
if (awsC !== undefined && prepareBaseImage === false) {
      await this._download(awsC.accessKeyId, awsC.secretAccessKey, awsC.region, awsC.bucketName, baseImage);
}
