Bugfix: Fix crash when suspending in shell during useSES re-render (#27199)

This adds a regression test for a bug where, after a store mutation, the
updated data causes the shell of the app to suspend.

When re-rendering due to a concurrent store mutation, we must check for
the RootDidNotComplete exit status again.

As a follow-up, I'm going to look into to cleaning up the places where
we check the exit status, so bugs like these are less likely. I think we
might be able to combine most of it into a single switch statement.
