ActivityTypeMaharamessage may throw php warnings

[Gold]

It looks like ActivityTypeMaharamessage may throw php warnings.

The __constructor() takes $data as an array. Phe parent::__constructor() treats it as an array. However, there is a check on $data where it is treated as an object.

Investigation needed to verify. At a minimum $includesuspendedusers is likely to always be false.
