No way to choose a different database when launching KeePassDX via Magickeyboard

**Describe the bug**
If you have 1+ databases but you have set KP to open one of them by default, you can tap on "back" arrow at the top of the screen to switch to the screen where you can choose a different database. This arrow is not present when launching KP via Magickeyboard.

**To Reproduce**
Steps to reproduce the behavior:
1. Go to a browser.
2. Switch to Magickeyboard
3. Tap on "key" button on Magickeyboard to launch KP
4. See the absence of thearrow

**KeePassDX (please complete the following information):**
- Version: 2.10.5
- Build: [e.g. Free]

Reproduce the launch flow from Magickeyboard with multiple databases and a default database selected. Trace the Magickeyboard launch entry point and compare its navigation with the normal KeePassDX flow; the issue is done when users can reach the database chooser and select a different database.
