These array keys are all meant to come from Parser::nextLinkID(). That
returns a positive integer. Let's please make the tests reflect what
the code actually does to reduce confusion.
I tried my best to come up with a mapping that still (possibly even
better) makes it obvious what's happening.

The first level in LinkHolderArray::$internals is indexed by numeric
namespace id. This must be a number. Let's please make the test
reflect what the code actually does.
Note the same mistake was already fixed before in I7e71ffc.
