fix(xo-server-backup-reports): fix undefined function in partial (#8229)

In some failure cases, backup reports were not sent because of an error during handlebars compilation.
The `formatDate` function was incorrectly passed from partial to partial causing the `executeFunction` helper to execute `undefined` as a function (the `vmFailure` helper used default `formatDate=./formatDate` instead of `formatDate=../formatDate`, the `..` being necessary because of the `#each` loop)
