Migration dialog contains placeholder text

Note

I am unsure if this is a valid report, as this disclaimer is only visible when modifying the launcher's files (as of right now). I am reporting this issue to confirm that this was not just forgotten about.

The bug

The migration dialog contains placeholder text. A screenshot is attached.

How to reproduce

First time

1. Ensure the Minecraft Launcher is not open, and that your device is not connected to the Internet
2. Navigate to your minecraft folder -> open launcher_accounts.json
3. Locate the line "eligibleForMigration" : false, and change the false, to true,
4. Save and exit the file
5. Open the Minecraft Launcher
   Notice how the dialog contains the placeholder text

Additional testing

The reproduction steps provided above only work for the first time this dialog has been opened. To test the issue again, complete steps 1-4 as above. After, complete the following:

1. Navigate to your minecraft folder -> open launcher_ui_state.json
2. Find the line containing MIGRATION_DIALOG, and change the true on that line to false
3. Save and exit the file

Then, proceed with step five from above.
