fix: resolve backport conflicts for version-15

install() holds the preset list inline on this branch, so the root is
resolved there instead of in get_preset_records. Dropping the preset-record
test with it -- there is no seam to call without running the whole installer.

The patch test is adapted to this branch: TestItem does not roll back between
tests, so it restores the original root name, and it passes parent_item_group
explicitly since ItemGroup.validate skips root-defaulting under
frappe.flags.in_test.
