Don't hardreset() game.advancetext in glitchrunner mode

This is the second part of what is necessary for credits warp to work.

The speedrunners call this "text storage". You need to get the
advancetext prompt up without a text box in order to be able to
increment the gamestate without bound. In 2.0, script.hardreset() reset
the text boxes, but not the prompt.
