Don't use using statements in Objective-C headers ... (#2827) use namespace aliases instead. This makes the Objective-C code much more like what it's going to end up being like when translated to C++: headers will include classes declared in a namespace relative to firebase::firestore so everything else will be named relative to firebase::firestore. Meanwhile the using statements in the headers were causing us to miss adding using statements in source files which was moving us away from where we wanted to be.
