SQLObject Update Whole benchmark - use obj.set

[scyclops]

Instead of:

orm-benchmarks/benchmarks/sqlobject/test_i.py

Lines 14 to 15 in ff2a587

	obj.level = choice(LEVEL_CHOICE)
	obj.text = f"{obj.text} Update"

Use obj.set like below for better performance from SQLObject:

obj.set(
  level=choice(LEVEL_CHOICE),
  text=f"{obj.text} Update"
)
