[Server] Don't use deprecated QSet methods and minor code improvements

Authored by ahmadsamir on Feb 13 2020, 10:09 AM.



Drop one usage of QSet::fromList(), and use QList::removeDuplicates()
instead, assuming the conversion for QList to QSet was to remove

Return early if nameValue is empty, this also guards against accesing
an out of bounds index.

Use QList::at() instead of [], to prevent detaching.

Test Plan

using sasl still works
