fetchThreadList error due to invalid value for ThreadColor

[RodriguesGabriel]

Description of the problem

When fetching thread list ValueError and FBchatException are raised probably due to the recently-introduced new Messenger colors (gradients).

Code to reproduce

# Example code
from fbchat import Client
client = Client("[REDACTED_USERNAME]", "a_password_with_%")
client.fetchThreadList()

Traceback

Traceback (most recent call last):
  File "C:\...\venv\lib\site-packages\fbchat\graphql.py", line 32, in graphql_color_to_enum
    return ThreadColor('#{}'.format(color[2:].lower()))
  File "C:\ProgramData\Anaconda3\lib\enum.py", line 309, in __call__
    return cls.__new__(cls, value)
  File "C:\ProgramData\Anaconda3\lib\enum.py", line 543, in __new__
    return cls._missing_(value)

    raise ValueError("%r is not a valid %s" % (value, cls.__name__))
ValueError: '#0edcde' is not a valid ThreadColor

During handling of the above exception, another exception occurred:

Environment information

• Python 3.7.1
• fbchat 1.4.2

As a quick fix I commented graphql.py line 43 where graphql_color_to_enum was called.

Should be fixed by #371, I'll make a new release momentarily :wink:
