find request returns expandable:1 on a leaf of a tree and it returns it as many times as many metrics in the glob

[azhiltsov]

metrics layout:
user.azhiltsov.test1.1
user.azhiltsov.test2.1

query:
/metrics/find/?query=user.azhiltsov.*.1
expected return:

[
  {
    "leaf": 1,
    "context": {},
    "text": "1",
    "expandable": 0,
    "id": "user.azhiltsov.*.1",
    "allowChildren": 0
  }
]

carbonapi returns:

[
  {
    "allowChildren": 0,
    "context": {},
    "expandable": 1,
    "id": "user.azhiltsov.*.1",
    "leaf": 1,
    "text": "1"
  },

    "leaf": 1,
    "text": "1"
  }

as the consequence expandable:1 grafana is offering you to 'select metric' even if you already at the leaf on a tree.
As consequence of multiple returns it offer you to fill the same values in the helper multiple times
