Remove "gb" from Aroma cafe, and possibly merge duplicate entries

[sjorford]

This Israel-based coffee shop chain seems to be listed twice with the same Wikidata ID:

{
  "displayName": "Aroma",
  "id": "aroma-5fc1d9",
  "locationSet": {
    "include": ["ca", "gb", "us"]
  },
  "tags": {
    "amenity": "cafe",
    "brand": "Aroma",
    "brand:wikidata": "Q2909872",
    "cuisine": "coffee_shop",
    "name": "Aroma",
    "takeaway": "yes"
  }
}

{
  "displayName": "Aroma Espresso Bar",
  "id": "aromaespressobar-1ae0cd",
  "locationSet": {
    "include": ["ca", "kz", "ro", "ua", "us"]
  },
  "tags": {
    "amenity": "cafe",
    "brand": "Aroma Espresso Bar",
    "brand:wikidata": "Q2909872",
    "cuisine": "coffee_shop",
    "name": "Aroma Espresso Bar",
    "takeaway": "yes"
  }
}

I can find no evidence that any such chain operates in the UK - there was an unrelated brand called The Aroma Cafe that was rebranded in the early 2000s, but there is no current chain called "Aroma".

A number of cafes/restaurants in the UK were incorrectly tagged, I have fixed and tagged them with not:brand:wikidata=Q2909872.
