Clean up code

- Set dropzoneOptions.url to arrow function which returns empty
string... url is required, but we don't use a restful api, we crop the
image and save the update file(blob) to an image

- set min-height of vuedropzone to 500px to be closer to the cropped
image and to center image overlay

- remove dz-message div, as one is already created automatically by
vue2-dropzone

webapp/components/TeaserImage/TeaserImage.vue
