The seed of the image placeholder is needed to generate the background
color of the image, but as the background color is later overriden any
seed could be used. When no text is explicitly given the seed is used as
text too, so there is no need to pass the user ID and simply using "?"
as seed is enough.

When calling the jQuery avatar plugin with a user that did not exist
(that is, users for which "/avatar/{user}/{size}" return a JSON response
with an empty "displayname" value) "?" on a grey background was shown.
However, if the jQuery avatar plugin was called with an undefined
JavaScript value then "?" was shown on a bluish background. This commit
unifies both cases to use the grey background.
The unit tests were also modified to ensure that the grey background is
used in both cases.

Calls to `sinon.stub(obj, 'meth', fn)` are deprecated and therefore
replaced by `sinon.stub(obj, 'meth).callsFake(fn)` as instructed by
the deprecation warning.
This makes the js unit testing output readable again.
