[TECHNICAL SUPPORT] LPS-49461 The Profile Pictures of the Users is no longer displayed by Chat

Hi,

In ChatPollerProcessor I create only half of the portraitURL, because there is no way (AFAIK) to get a valid ThemeDisplay without a HttpServletRequest, and there we don't have one. So the rest will be added in main.js were we have a ThemeDisplay.

Br,
Norbert
