Embedding: "username for topic creation" is not required

[michaeld (Michael - Communiteq)]

The “username for topic creation” is currently not a required field in the embedding settings.
However, without that value, embedding will not work.

There is a check for valid username on that input field, it should be checking for not-empty as well ?

Good point, @eviltrout can you have a look?
