Regresson since 7.5.2 - global message declaration has priority over nested message declaration

[ziggi]

Since 7.5.2 version global message declaration has priority over nested message declaration.

Example + reproduction:

message NestedMessage {
  int32 id = 1;
}

message TestMessage {
  message NestedMessage {
    int32 id = 1;
    string name = 2;
  }

  NestedMessage nested = 1;

  // this one will work properly
  // TestMessage.NestedMessage nested = 1;
}

const data = {
  nested: {
    id: 0,
    name: 'hello',
  },
};

const encoded = TestMessage.encode(data).finish();
const decoded = TestMessage.decode(encoded);

console.log('encoded', Array.from(encoded));
console.log('decoded', decoded);

The result is:

encoded [ 10, 2, 8, 0 ]
decoded TestMessage { nested: NestedMessage { id: 0 } }

but it has to be:

encoded [
   10,   9,   8,   0,  18,
    5, 104, 101, 108, 108,
  111
]
decoded TestMessage { nested: NestedMessage { id: 0, name: 'hello' } }
