Missing authorship information

[zarvox]

Reproduction:

• User 1 creates new etherpad grain
• User 1 creates new sharing link via share access button
• User 2 (who is already logged in) opens that link
• User 1 types into the window
• User 2 sees that text attributed to "Unknown Author". I would expect it to show User 1's display name.
• User 2 types into the window
• User 1 sees that text attributed to "Unknown Author". I would expect it to show User 2's display name.

If User 1 refreshes the page, the apparent authorship information is corrected for both users. (I didn't test what happens if User 2 does likewise; I imagine it would probably also fix the attribution labels.)

In the screenshots below, Alice Dev Admin is User 1 and Dave Dev User is User 2.
