Follow up fixes for Improving Chat Message Search

[rapterjet2004]

• fixes Followup improvements for search for chat messages #4885

---

• Failure to find message id in db creates the context chat compose
• Rotating the device leads to some wrong design & search window is closed.
• Some file icons are not yet displayed as expected. For example on sermo in the "Filetype examples" (e.g. icons for zip files..)
• Extract and add Compose Previews for each message type (will require a lot of a refactoring)
• Test it out

🏁 Checklist

• 🔖 Capability is checked or not needed
• 🔙 Backport requests are created or not needed: /backport to stable-xx.x
• 📅 Milestone is set
