average_temperature from current_daily_data can be None

[llluis]

Describe the bug
If you query HQ close to midnight, data is still being rolled out.
One corner case is already taken care of (yesterday - 1).
But, HQ will release the consumption without average_temperature.

If you query during this interval, you get None and code can crash.

Traceback (most recent call last):
  File "/usr/local/bin/pyhydroquebec", line 8, in <module>
    sys.exit(main())
  File "/usr/local/lib/python3.7/site-packages/pyhydroquebec/__main__.py", line 168, in main
    output_text(results[0], args.hourly)
  File "/usr/local/lib/python3.7/site-packages/pyhydroquebec/outputter.py", line 24, in output_text
    print(YESTERDAY_TPL.format(d=data))
TypeError: unsupported format string passed to NoneType.__format__

To Reproduce
Run the std use case

pyhydroquebec -u XXX -p XXX

Expected behavior
No errors. :)

PyHydroQuebec and Python version
Python 3.7.5
PyHydroQuebec 3.0.0 (master as of today)

Corner Cases
Are you in one of this situations:

• Change of address
• Change of rate
• Add a new contract
• Remove an old contract
• No
• Other: query close to midnight (2AM in my test)
