bugfix for dict based identity

[pall-valmundsson]

When using a dict object to represent an identity the default jwt_encode_callback handler fails as getattr does not work with dict objects. This change sets the default value of getattr to None so the dict get part of the statement is evaluated.

The tests required a different implementation of the app fixture.

I have run into the same error when retrieving identity from RethinkDB, which return in dict.

I would create my own PR if I did not find this PR.

by the way, how about make it this way

identity = getattr(identity, 'id', None) or identity.get('id', None)

feel more robust

Wish it being merged soon.
