Focus_Index_Before_Search doesn't work as intended

[Rohitth007]

Suppose one is currently focused on the 10th Stream. After "escaping" search it is expected that the focus is back on the 10th Stream but it rather focuses on the stream it was in focus during the search right before escaping.

This is also related to the crash in #923

@neiljp Also, wanted to ask if this feature is necessary because if you press q when u are at All messages or Middle Column or Right Column there is no way of knowing which was in focus as each of these are different ListWalkers

@zulipbot add "further discussion required"

ERROR: Label "further discussion needed" does not exist and was thus not added to this issue.
