* telegram: Remove implicit value for entity_cache in function declarations,

if entity_cache already existed was not assigning the default value so was

confusing. Add comments to explain that entity_cache should be a list.

- async def get_channel_topic(self, channel, entity_cache=[None]):

+ async def get_channel_topic(self, channel, entity_cache):

+ # entity_cache should be a list to be a persistent and by reference value

- async def get_channel_creation(self, channel, entity_cache=[None]):

+ async def get_channel_creation(self, channel, entity_cache):

+ # entity_cache should be a list to be a persistent and by reference value
