Undertale: Various Fixes (#2146)

* Changed the pathing code to use os.path.join, instead of adding strings together, also fixed the savepath command using UndertaleContext instead of self.ctx (Credit to Wackerly for finding the self.ctx issue and fix)

* Undertale: Fixed a debug function in the game not requiring debug to be enabled.

* Undetale: Fixed a logic bug with the location "Letter Quest"
