Previous Behavior

Previously, Salt would fail when applying a second state of file.managed like so:

DESKTOP-P56BQAV:
----------
          ID: dump_secret
    Function: file.managed
        Name: C:/random.bin
      Result: False
     Comment: Unable to manage file: 'ascii' codec can't decode byte 0xc0 in position 24: ordinal not in range(128)
     Started: 11:22:52.481000
    Duration: 20.0 ms
     Changes:

New Behavior

Now, salt will report the file is in the correct state since no change has been made on it:

DESKTOP-P56BQAV:

    Function: file.managed
        Name: C:/random.bin
      Result: True

FWIW this could be rewritten using tempfile.NamedTemporaryFile, to avoid the try/except to try and cleanup.
