Bug 31569: Remove GetImportRecordsRange from list step

This patch removes the use of GetImportRecordsRange from the step
of listing import batches to choose. It was only used for a count so is a simple
replacement

To test:
1 - Stage a number of files for import
2 - Import one of the files from tools
3 - Add to basket form a staged file
4 - Confirm staged baskets are listed, and imported basket is not
