With the new avatar endpoint there is no difference between unknown
users and errors when generating the placeholder avatar. Therefore the
avatar function will now show the old placeholder if both a user and
displayname was given as parameters.
In case there is no displayname provided we cannot build the proper
placeholder so the unknown user placeholder is shown.
The displayname is not required for the avatar anymore, so we can
get rid of the old code path for placeholders.

The js and php code differ ever so slightly. So having the placeholder
for a second and then the image is just weird.

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.

Fixes#4087
Because of fancy javascript if a full numeric uid was used javascript
would convert this to an int. Now we just convert everything to a string
first.

Old code first dit an ajax request to the avatar. Then a new image
object with the same src was created and since we do not cache avatars
yet :( this resulted in 2 sequential requests to the exact same URL
Now if you set the displayname it will first set the placeholder and
then load the avatar in the background. Only once this time!
