fix: prevent overriding active channel UI on ChannelList pagination error

[MartinCupela]

🎯 Goal

Developers, who worked on Channel.tsx implemented the logic of what is displayed in Channel component coupled to what happens in the ChannelList pagination (not SDK development, but app development pattern). This PR prevents overriding Channel UI just because during the channel pagination an error occurred. It is rather unexpected from the app user point of view to loose the all the information in the chat just because the one page of items could not be solved in the channel list sidebar.
