PATCH with multiple INSERT statements do not add all data

When sending the following PATCH request:

INSERT DATA {
  <https://drive.verborgh.org/solid/card#me> <http://xmlns.com/foaf/0.1/name> "Ruben1"
}
;
INSERT DATA {
  <https://drive.verborgh.org/solid/card#me> <http://xmlns.com/foaf/0.1/name> "Ruben2"
}
;
INSERT DATA {
  <https://drive.verborgh.org/solid/card#me> <http://xmlns.com/foaf/0.1/name> "Ruben3"
}
;
INSERT DATA {
  <https://drive.verborgh.org/solid/card#me> <http://xmlns.com/foaf/0.1/name> "Ruben4"
}
;
INSERT DATA {
  <https://drive.verborgh.org/solid/card#me> <http://xmlns.com/foaf/0.1/name> "Ruben5"
}
;
INSERT DATA {
  <https://drive.verborgh.org/solid/card#me> <http://xmlns.com/foaf/0.1/name> "Ruben6"
}

only some of those statements are added. A possible result is:

@prefix : <#>.
@prefix n0: <http://xmlns.com/foaf/0.1/>.

:me n0:name "Ruben1", "Ruben3", "Ruben6".

使用 issue 中显示的 PATCH 请求以及全部六条 INSERT DATA 语句进行复现，并检查生成的 Turtle 数据。跟踪请求处理和更新处理，直到找到语句被丢弃的位置；当六个 name 值全部被存储，并且该行为由回归测试覆盖时，即表示完成。
