  [acc] added loose dependency to dialog module

We need to be sure that dialog module is init before acc (if dialog is loaded), to prevent any crashes when acc registers the DLGCB_LOADED callback in dialog (the registraion of the callback will try to run the callback on any pre-existing dialogs, so the hash table for the dialogs must be created/init).
It is a loose dependency as it does not require the dialog module to be loaded. But if loaded, it must be init before ACC module.

Fixes #1833
