sleep() and wake() throw errors on Blinka

Duplicating #42 since it cannot be re-opened.

This is effectively the same as adafruit/Adafruit_CircuitPython_DisplayIO_SH1106#17, with the same repro code.

import board
import displayio
import i2cdisplaybus
import adafruit_displayio_ssd1306
from time import sleep
import traceback

displayio.release_displays()
i2cBus = board.I2C()
display_bus = i2cdisplaybus.I2CDisplayBus(i2cBus, device_address=0x3C)

WIDTH = 128
HEIGHT = 32

# create the display and put it to sleep
display = adafruit_displayio_ssd1306.SSD1306(display_bus, width=WIDTH, height=HEIGHT)

print(f"Wake> {display.is_awake}")
try:
    print("Sleep")
    display.sleep()
    print("No error")
except Exception:
    print(traceback.format_exc())

sleep(.5)
print(f"Wake> {display.is_awake}")
try:
    print("Wakey")
    display.wake()
    print("No error")
except Exception:
    print(traceback.format_exc())
