Add New Container view allows creating samples without protein

[jlmuir]

I've been told that a sample must always have a protein assigned, but the "Add New Container" view (i.e., /containers/add/did/<id>) allows creating samples without a protein.

Steps to reproduce:

1. Click the "Add Container" button from the Shipment view.
2. Select a container from the Registered Container drop-down menu.
3. Enter x1 in the Name column of sample location 1.
4. Click the "Clone from First Sample" button.
5. Click the "Add Container" button.

Actual Result:

It creates the container with the samples with no proteins assigned.

Expected Result:

It should produce a validation error that no protein is selected from the Protein Acronym drop-down for the samples.

Inspecting the DB, it seems SynchWeb creates the container but does not actually create the samples. The samples are silently lost; no error message.

Seems to be no longer possible on the vue-style container pages.
