DNA ADDRESS != DNA entry address

[Connoropolous]

building off of https://forum.holochain.org/t/dna-address-dna-entry-address/2834

Use case was trying to link off of hdk::DNA_ADDRESS, but that didn't work because it suggests that no entry with that address is found.

Here are steps to reproduce...

1. clone https://github.com/Connoropolous/holochain-dna-bug-reproduce
2. in the folder, launch nix-shell, nix-shell https://holochain.love
3. Run npm run hc:test

Looks like the reason may be that the commit of the DNA commits this: https://github.com/holochain/holochain-rust/blob/420fe08c4dfac8f3281e5139e199d7626a142090/crates/core/src/nucleus/actions/initialize.rs#L87-L89

where dna is wrapped in Entry::Dna

Thanks @Connoropolous & @ddd-mtl. Note that in general linking off the DNA address is considered an anti-pattern because it will create a definitive dht hot-spot. Of course for small hAapps it can be useful, and this shouldn't be failing like that.
