In a channel feed, if you tap the compose box and the topic input is empty (i.e. you haven't already entered something there), we'd like to put focus in the topic input instead of in the content input.

Chat thread here: #mobile > reply goes to "no topic" @ 💬

Background / motivation

This bit of user feedback started that same thread:

Hello, a new user / first time poster with some hopefully useful feedback : we moved a small organisation to Zulip recently and the thing we keep banging our heads on is accidentally posting to [no topic] when we meant to reply to a comment in some topic.

In the legacy app we effectively have the behavior this issue is calling for: when the compose box is closed, the topic input doesn't even appear, but once you touch it so it opens, your focus goes to the topic input.
