Bug 880624 - [MMS/SMS] The dialog when tapping on a contact into ‘To’ field is not correct

Disambiguation screen as suggested by Ayman

As we are using the CustomDialog coming from shared, we have two main components:
title: We used the display name
message: We are using the text showed to disambiguate the contact in the contacts suggestions

Also the semantic of the CustomDialog forces us to put a 'negative' option on the right hand side (instead of the left) as was in the wf.

All this has been reviewed and approved by Ayman.
