getUserBlogs returning invalid response for OLW

[darenm]

Trying to add a miniblog.core blog to OLW returns the following error:

[adricadar]

I found the culprit.
It comes from MetaWeblogService when it tries to use get the blog name _config["blog:name"] it doesn't exist and the exception is thrown.

There are 2 possible solution to solve this:

1. The easiest one, in the appsetings.json file, under the blog add property name.
2. It's a guess, but I think the owner was supposed to be there, as following _config["blog:owner"]

I can make the changes, but which one is the desired one in this case? (my preference is 2)
