Fix loading avatar images by request by batch

[kerto07]

Too many http requests are done at the same time to get the avatar images, instead I do the same by batch of 50 so it is not too much. Also there were issues with special characters in the url for keybase, I passed the query string parameters in qs variable to fix that

Take a closer look - in the current version, avatars are loaded in turn one at a time

We deliberately did not loading with batches in order not to load the api and avoid unsuccessful requests

Also there were issues with special characters in the url for keybase, I passed the query string parameters in qs variable to fix that - Yes, that's great! Let's use it

Actually it doesn't load one at a time because there is no await when calling cacheAvatar()

I tried before with the await cacheAvatar(), it worked but it was slow, so I loaded by batch. If it is ok to be a bit slow, then we can just add the await when calling cacheAvatar(), it will fixes some network issues

Yes, it looks like a missing await - will need to add await before cacheAvatar

@potvik if no issue with batch load why not using it ?

@kerto07 @sophoah we can decrease batch to 10.. i think it should be ok. Another way - return to base version. and add await before cache.
