This is a preparatory commit for using isort for sorting all of our
imports, merging changes to files where we can easily review the
changes as something we're happy with.
These are also files with relatively little active development, which
means we don't expect much merge conflict risk from these changes.
This fixes a bug where the endpoint for editing bot users would allow
an organization administrator to edit the full name of a bot user.
A combination of this an another recently fixed bug made it possible
for this process to set a `bot_owner` for a non-bot user; so we also
include a migration to fix that for any users that might have had our
model invariants corrupted in that way.
