proper indentation of license under "this file is my own work"

Due to the use of <br /> in mwe-upwiz-license-cc-zero (i18n), the
indentation of third label (cc0 waiver) under "this file is my own work" got disturbed.
So to fix that, added the class 'mwe-upwiz-copyright-info' at line 237 of UploadWizardLicenseInput.js
