**Problem**: When I create a hosted diffusion repository, before activating the repository, the bare diffusion UI throws an error if I leave the edit page.
Steps to reproduce:
# Create a new, hosted repository, with lots of great names and stuff.
# When the UI asks you to 'Activate Now' or continue editing basic info, edit the basic information.
# Maybe add a description to the repository, and some other stuff (autoclose branches, etc)
# Without activating the repository, navigate to any other page.
# Then, navigate back to the repository, e.g. `/diffusion/xyz/`
# Where you'd normally see some info (Like `Commits Importing` or something if it was activated), you see an error: `File system entity '/var/phabricator/repos/XXX/' does not exist.` For example, just click on the Breadcrumbs in the UI of the edit screen to go to the repository itself. Screenshot attached.

Note: the `unresolved error` messages are from the most recent upgrade, because all the clustering work is deprecating the `notification.*` settings, etc. I simply upgraded to make sure it was existing on both the old version and HEAD before reporting.
**Note**: This bug is not particularly egregious, and most people likely won't hit it very often (because they can just hit back in their browser, or will just hit `Activate Repository` anyway). But it's kind of ugly in the UI and maybe you want to catalog it for a fix some day.
**Workaround**: Hit Back in your browser. or just append `edit/` to the end of the URL (e.g. `/diffusion/2/edit/`)
