Client crashed after editing qualifier result

Bug description

The game will be crushed if you quit "edit seeding result" fast enough by opening an "incomplete" team. The game version is a special version given on #20781, but I guess the latest stable lazer version have same error.

Steps to reproduce:

Edit braket.json under the tournament's file folder, and add an incomplete object to the Teams array, with only the necessary attributes contained. the following object is an example, as you can see, missing BeatmapInfo and other things not necessary :

{
  "FullName": "Myon_",
  "FlagName": "16626025",
  "Acronym": "16626025",
  "SeedingResults": [
    {
      "Beatmaps": [
        {
          "ID": 3831056,
          "Score": 973381,
          "Seed": 10
        }
      ],
      "Mod": "SV",
      "Seed": 10
    },
    {
      "Beatmaps": [
        {
          "ID": 3831047,
          "Score": 958216,
          "Seed": 60
        },
        {
          "ID": 3831054,
          "Score": 981045,
          "Seed": 34
        },
        {
          "ID": 3831046,
          "Score": 952202,
          "Seed": 60
        }
      ],
      "Mod": "RC",
      "Seed": 48
    },
    {
      "Beatmaps": [
        {
          "ID": 3831043,
          "Score": 970222,
          "Seed": 26
        },
        {
          "ID": 3831045,
          "Score": 971863,
          "Seed": 21
        }
      ],
      "Mod": "LN",
      "Seed": 23
    },
    {
      "Beatmaps": [
        {
          "ID": 3831058,
          "Score": 965141,
          "Seed": 39
        },
        {
          "ID": 3831057,
          "Score": 942703,
          "Seed": 48
        }
      ],
      "Mod": "HB",
      "Seed": 45
    }
  ],
  "Seed": "28",
  "LastYearPlacing": 1,
  "AverageRank": 7264.0,
  "Players": [
    {
      "id": 16626025,
      "Username": "Myon_",
      "country_code": "CN",
      "Rank": 7264,
      "CoverUrl": "https://assets.ppy.sh/user-profile-covers/16626025/f15da64b322b32fd5ca511c3291d9cabaa2ea256eadb850402040444fcb0fdae.jpeg"
    }
  ]
},

open lazer tournament client, click "team Editor", select any team with incomplete information, and click "edit seeding results."
fast click "back" before information is downloaded and completed.
Error information rasing to the bottom and the game is crushed. if you waited until the information was completely downloaded or opened a "finalized" team. the game won't crush. as the gif shows. click teams called "Riemann" won't be caused crushed but "Myon" dose so. another experiment shows if waited long enough, "Myon" is also not crushed.
