fix: backwards compatible with remote selection

[lawvs]

Fix the error log in toeverything/AFFiNE#4980

slot.js:99 [
  {
    "code": "invalid_type",
    "expected": "boolean",
    "received": "undefined",
    "path": [
      "isReverse"
    ],
    "message": "Required"
  }
]

Since the remote data is unreliable, we should ignore the error when parsing failure.
