Parachains registered at IDs other than 0 do not collate

[JoshOrndorff]

The example parachain node has a hardcoded ID of 100. When I follow the instructions to register the parachian, I use id 100 as instructed, and the registration extrinsic completes successfully. However, the collator does not begin collating. One hint from the relay chain node logs is Local parachain duty is Some(LocalDuty { validation: Parachain(Id(0)) }). I expected that value to be 100, not 0.

Second Attempt
Kill all parachain and relay chain nodes, and purge all chains. Start the relay chain again. Start the Collator again, this time try to register at id 0 despite the hard-coded id 100 in the collator code.
Same behavior as before. Now, the collator actually starts producing blocks despite the mismatch between hard-coded id and registered id.

Third Attempt
Modify the collator node to hard-code id 0, and recompile. Kill all nodes and purge all chains. Re-start the relay chain. Re-start the collator. Register at id 0. As in the second attempt, the collator now begins producing blocks as expected.

Also just noticed that the non-hacked collator itself reports ID(0) upon startup.

Works for me. Probably was related to not being up-to-date.
