Sanitize username and photo URL

Browse source 
HedgeDoc displays the username and user photo at various places
by rendering the respective variables into an `ejs` template.
As the values are user-provided or generated from user-provided data,
it may be possible to inject unwanted HTML.

This commit sanitizes the username and photo URL by passing them
through the `xss` library.
