fix: make initial message pagination state pesimistic

[MartinCupela]

Goal

The message set, when initiated, should receive pesimistic pagination indicators, meaning that it should expect there is no more data to load. This is of course adjusted with the first channel(s) query. It is logical, that in order the message list that paginates over messages to be showed, first the channel data has to be queried.
