Description of problem:
From Legacy ContentHost UI > Chost > Errata Tab

We cannot see the content-view name in the 'Environments' Dropdown.
We can see the environments name, and any previous/Library environment, 
but the content-view name displayed is 'undefined'. 
Only seems to affect this page.

Version-Release number of selected component (if applicable):
Stream snap 59.0 (6.16)
6.15.1 snap 1.0{}

How reproducible:
Always

Steps to Reproduce:
1. Associate an activation-key with a published content-view, only in 'Library' environment. Register a contenthost to the activation-key.

2. Create a new lifecycle environment, with prior being Library.

3. Publish the existing content-view-version into the new environment.

4. Go to Legacy ContentHost UI > Chost > Errata Tab

Actual results:

• In the dropdown for 'Environments' we can see the following options:
     'Library Synced Content'
     'Previous Lifecycle Environment (Library/undefined)' <<
     'Current Lifecycle Environment (lce_1/undefined)'    <<

• But the content-view name appears correctly in other places, 
    like Legacy ContentHost UI > Chost > Details > Content Host Content.

Expected results:

• In the dropdown for 'Environments' we would expect the options:
     'Library Synced Content'
     'Previous Lifecycle Environment (Library/CV_0)' <<
     'Current Lifecycle Environment (lce_1/CV_0)'    <<
