Prevent unsafe name-based constructor-injection

[mindplay-dk]

Name-based injections currently are globally available, which is risky.

$c->register("foo", "Foo");

$c->register(Bar::class);

class Bar {
    public function __construct(NotBar $bar) {}
}

The risk here, is that constructors may accidentally have something injected just because the parameter name happens to match, which is risky, and (in our experience) not very useful - in practice, using a less-general (usually qualified with .) component name is much more common, is safer, and makes for more readable registrations.

The ability to resolve arguments to factory closes by name must of course be preserved.

Fixed in 2.0 release.
