_s3_create handles image being deleted

Change so _s3_create handles the image it is creating
being deleted while it is creating it without logging a stacktrace
and instead just logging a simple message explaining what happened.

Add fake_instance.py

There are lots of places in the tests where we create a piece of
an instance-like dict and return that from a stubbed database
function. This "works" right now, but won't in the future of stricter
objects. This adds a fake_instance.py (to mirror the other ones
already there) which builds an instance database primitive that
includes sane values for every field it should have. This will make
testing much easier going forward with instance objects.

Make instance object tolerate isotime strings

Any time we get a db object over RPC, the datetime has been
serialized to an isotime string. We have other legacy code that
needs to tolerate this, and those hacks would need to be
replicated in the objects transition. Instead, make the instance
object type function tolerate isotime-formatted strings so that
we can more easily convert RPC-transited database objects
until we're fully converted, at which time we could remove the
tolerance. Luckily, the objects still end up with a datetime
internally, which means the rest of the code can stop needing to
handle strings and datetimes gracefully.
