Always use the channel title for the first breadcrumb

[bjester]

Summary

Description of the change(s) you made

• When changing the title of a channel, the name in the breadcrumbs wasn't updating because that was saved into the content node table of IndexedDB with the channel's original title. Instead of having that require updating in IndexedDB, I've simply removed that functionality and made the first breadcrumb always use the channel's name

Manual verification steps performed

1. Open a channel for editing
2. Click to edit the channel details
3. Update the channel's name
4. Save the changes
5. Verify the breadcrumbs have also been updated

Fixes #3295
