re-enable glance notification tests

introduced in Id049b6cb8ab3092c50f35894cf5a6bda7ff04617 and
disabled by I763212bad849980bea7fdb96384a5fba7889cce7

improvements to sql backend were made in Juno (see bug)

this patch re-enables the tests and makes a modification to the
expected list of meters (some of original meters are deprecated)
