When we fetch the pages per wiki, the API returns an object that
defines the local wiki we are in as its dbName; this then gets
stored into the model as the source, which forces us to check against
the dbName whenever we want to perform an operation so we can tell
the API layer to fetch and perform the actions locally, rather than
use a foreign API.
The term 'local' makes no sense for naming the model (and upcoming
tech debt work will fix this) but it makes sense in the context of
the API layer -- and hence, the source name should follow suit.
This fix makes sure that the local wiki objects always have their
sources defined to be 'local', and thus making us use the test for
dbName in very specific points (when we get the data) rather than
throughout the codebase, randonly.
This is also the first step to allow proper updating of things like
seenTime accross wikis, especially in cases where we view a remote
wiki as if it is local (in the Special:Notifications page)

Add a sidebar with cross-wiki sources and pages of unread notifications.
The filter allows the user to fetch notifications from a foreign source
and specific pages if those exist.
