Added tests for dynamic choice options for the Unknown Tomb

[Veracity0]

On the Nemesis Quest, the first task is to retrieve your Epic Weapon from the Tomb of the Unknown CLASS.
You adventure in the Unquiet Garves until you encounter the tomb.
On the door is a riddle with three (class-specific) answers.
The order of the answers (i.e. the choice option #) is shuffled every time you refresh the page.
ChoiceManager has special handling for automating this choice to choose the (currently) correct option.

This test has three saved HTML files with the correct answer in option 1, option 2, and option 3.
It verifies that we pick the correct option in each case.
