[TASK] Improve usability of user/group select in log module

Instead of prefixing the type (user, group) for every option an optgroup
is used. With this change it is possible to use the keyboard to jump to
a specific letter.

Furthermore BackendUtility::getRecordTitle is used to retrieve the label
instead of using a hardcoded field name.
