Confluence Clustered DC Restore from Backup incorrectly reading from <Local Home>/restore folder

Issue Summary

When performing the Restore from Backup during the initial Confluence installation, the setup screen advises to place the XML Backup into the <Shared Home>/restore.

However, it doesn't show any files in the <Shared Home>/restore as it's looking in the <Local Home>/restore.

This is reproducible on Data Center: Yes

Steps to Reproduce

1. Install a fresh Confluence instance
2. Apply a Confluence Data Center license
3. When prompted for Non-Clustrered or Clustered - choose Clustered
4. Follow the remaining prompts until you reach the Load Content screen
   • Choose Restore from Backup
   • The screen will advise to place the XML backup into <Shared Home>/restore
   • Place your XML Backup into the <Shared Home>/restore and reload the page

Expected Results

The screen will pick up and list the XML backup from the <Shared Home>/restore in the bottom box.

Actual Results

The screen does not pick up and list the XML backup from the <Shared Home>/restore in the bottom box.

Only when you put the XML Backup into the <Local Home>/restore, then the XML backup file is picked up.

Workaround

During the initial install of a Confluence Clustered DC installation, place the XML backup in the <Local Home>/restore and reloading the setup dialog should pick up the file.

If you are doing a Restore after Confluence DC is already up and running through Confluence Administration » General Configuration » Backup and Restore screen - the correct location that the dialog is showing and reading the XML backup from is the <Shared Home>/restore.
