[Regression] Registration not working in 1.0.28

[PawlikMichal25]

So because of issue #444 and then PR #446 registration stopped working with Parse returning:

ParseException (Type: PasswordMissing) :
Code: 201
Message: password is required----

This can be easily fixed by adding here:

      final Map<String, dynamic> bodyData = _getObjectData();
      bodyData['password'] = password;
      final Uri url = getSanitisedUri(_client, '$path');

but I wonder if this the approach we wanna take? Or if there are other things broken because of that?

I think, as this is the only time where _objectData is directly accessed by ParseUser, we should be fine by doing your change.
Edit: But, I would replace bodyData['password'] = password; with bodyData[keyVarPassword] = password;
