fix(db-update): prevent blank screen when updating 2.0.6 to 2.1.0

[kevinwhoffman]

User Story

As a Give user, I want a clear indication of the update progress after I initiate the database update so I am confident it has completed.

Current Behavior

I currently see a blank screen after initiating the update. During the blank screen, if I click the Updates menu item in the left menu, I get a permission error. See visuals below.

Expected Behavior

I expect to see progress of the update.

Steps to Reproduce

1. Install Give 2.0.6
2. Update to Give 2.1.0.
3. Initiate the database upgrade.

Visuals

Blank screen when DB upgrade is initiated

Permission error when Updates menu item is clicked

Possible Solution

@ravinderk mentioned this might be because the upgrade has completed before the page has had a chance to render. If that's the case, we should still communicate that the update completed successfully.
