Don't be too strict when resolving the DB data

We could just use makeTitle() since the data is coming
from the database, we can assume it's valid title

WikiReference::fromStorageRow() was using MakeTitleSafe.
If for some reason some invalid title made it in, this would
case PHP errors (constructing WikiReference object a couple
lines down typehints for Title objects but would receive null).
So switch to MakeTitle().
