Do not raise SIM115 when a file is closed immediately?

[harupy]

The following code violates SIM115:

open("a.txt", "w").close()  # create or reset a.txt

# a.py:1:1: SIM115 Use context handler for opening files

I'm wondering if SIM115 should not be raised in this case. We could use the following as a workaround:

with open("a.txt", "w"):
    pass

Yeah, I think we should allow this.
