Fix channel list parsing failing completely if one channel fails parsing

Resolves https://github.com/GetStream/ios-issues-tracking/issues/355

🎯 Goal

Adds some protection when parsing the channel list. With this change, if one of the channels fails to parse, it won't completely discard the channel list.

🛠 Implementation

We already have a mechanism to avoid this, but it was not being applied in all cases, and most importantly, it was not being applied to the ChannelListPayload so that if a channel fails to parse, it will skip it and return the other channels.

🧪 Manual Testing Notes

This is only reproducible by overriding the HTTP Responses through Proxyman.
Either way, unit tests were added to cover this scenario.
