I'm seeing the same issue.
My client subscribes to receive the notifications, the server publishes a notification, but it's not received. :|
It seems that this issue is caused by Effort not supporting some datetypes, as per <a class="postlink" href="https://github.com/tamasflamich/effort/issues/10">https://github.com/tamasflamich/effort/issues/10</a>
I resolved the issue by removing all DataType annotations.

I've run into the same issue trying to run any of the tests using version 0.10.3.0 of Abp. How did you resolve the issue?
Cheers, mike
FWIW I found that I also needed to add a custom validator in my UserManager ctor to be able to use non-alphanumeric characters in the username:
this.UserValidator = new UserValidator<User,long>(this) { RequireUniqueEmail = false, AllowOnlyAlphanumericUserNames = false };
