integration tests: make the group name unique when grouping shares

To avoid various name caching issues existing tests were adding a unique
suffix to smb shares. However, now with explicitly named share groups
the `spec.scaling.group` field determines what the name of generated
resources will be. Increase test reliability by adding the unique suffix
to the name of the group too.
