Calling `ns.remove(node)` on renamed nodes does not work.

[runeh]

protobuf.js version: 7.3.2 and newer.

Steps to reproduce:

• Find a Type object in the tree: const myType = ns.lookupType('.MyType')
• Change its name: myType.name = "NewName"
• Remove the type from the parent: myType.parent.remove(myType)

Expected:

• The type is removed from the parent, and no longer in the nestedArray property

Actual:

• The type is still a child of the parent

I've added a test in a fork: runeh@a04e6ea

I assume it's due to this line:

protobuf.js/src/namespace.js

Line 261 in 59569c1

delete this.nested[object.name];

The remove code assumes that the name will not have changed between the node being added and removed.
