'KeyError': index out of bounds on patch.remove

[alejandromumo]

This bug relates to the following lines:

dictdiffer/dictdiffer/__init__.py

Lines 315 to 319 in 6719335

	dest = dot_lookup(destination, node)
	if isinstance(dest, SET_TYPES):
	dest -= value
	else:
	del dest[key]

Description:

• destination is an array that is constantly mutated by dest[del]
• key is computed in an outter scope. On Zenodo, it's pre-computed based on the original field's array (e.g. 'authors' of a deposit).
• At some point, the array might be smaller than the original one and dest[key] can raise a IndexError. This was observed when a deposit had multiple changes to the author's list.
