Save quote to favorites throws error

[stueja]

When I try to save a quote to favorites via Quotes > Save to favorites, variety replies with Oops, something went wrong when trying to save the quote to favorites.
The logfile states

Traceback (most recent call last):
  File "/usr/lib/python3.7/site-packages/variety/VarietyWindow.py", line 2518, in quote_save_to_favorites
    f.write(text.encode('utf-8'))
TypeError: write() argument must be str, not bytes

This is version 0.7.0 on Arch Linux.

This is a duplicate of #85, but I've gone ahead and made a new release now.

Ah. I was searching for that, but only in open issues.
