REST API for group: kwargs are not the displayed one in exception

[moobyfr]

Using groups_members I was confronted to the name of the variables

I can use groups_members(group="foo"), but not groups_members(roomId="bar")
using the second call, I get an exception
RocketMissingParamException: roomId or group required

THE REST API allows usage of roomId

The current workaround is to use groups_members(room_id="bar")

We use only the required parameters for every endpoint explicitly in code. This means we will be specifically checking for group or room_id. In the end, room_id is transformed to roomId under the hood so it basically is the same. The idea was to use a naming schema following as much as possible Python's standards.
