`Function`'s and `FunctionHeader`'s `reset_last_change()` does not call the `super()`'s function

[themaks]

When reset_last_change() is called on a Function or FunctionHeader, it iterates over their arguments', stackvars' and header's own reset_last_change(), but it never actually apply the useful modification (self.last_change = None) to themselves.

Function.reset_last_change and FunctionHeader.reset_last_change should also call super().reset_last_change():

• In Function:
  

  declib/declib/artifacts/func.py

  Lines 352 to 359 in cd38076

  	def reset_last_change(self):
  	if self.header:
  	self.header.reset_last_change()
  	if self.stack_vars:
  	for sv in self.stack_vars.values():
  	sv.reset_last_change()

• In FunctionHeader:
  

  declib/declib/artifacts/func.py

  Lines 128 to 132 in cd38076

  	def reset_last_change(self):
  	if self.args:
  	for arg in self.args.values():
  	arg.reset_last_change()

Actually the comment in their respective super-class, Artifact tells us this was intended, but forgotten:

declib/declib/artifacts/artifact.py

Lines 277 to 283 in cd38076

	def reset_last_change(self):
	"""
	Resets the change time of the Artifact.
	In subclasses, this should also reset all artifacts with nested artifacts
	"""
	self.last_change = None
