Removed ensuring there is a target in getTarget(), which solves a crash when debugging in PyCharm. *Previously if an Unit was opened during debugging it would crash if the unit had no target, failing the assertion. *If there is no current target getTarget() will instead return itself (this functionality was already implemented and probably how it handled it before adding this assertion)
*I have done some basic tests and now Unit can be opened BUT in some cases it crashes upon inspecting a target of a unit. However this alteration is still better as it does just SOMETIMES crash instead of ALWAYS
