(imported) text in front of the name is added when using new UI after importing world

When importing your world with .mcworld, using the import world button in the new UI, the world name has added the (imported) name in front of the main name, even though it is redundant. This wasn't the case when using the old UI.

Steps to Reproduce

1. Enable new UI for the World selection UI.
2. Import any world (with .mcworld extension) by pressing the import world button.
3. Wait until the import world process is complete.

Observed Result
The world name has (imported) name added to it.

Expected Result
The world name doesn't add the (imported) name to it.
