[Mentions v2] Replace/remove room mentions name based when creating new reportActions

[rlinoz]

When creating a new reportAction we need to identify room mentions that are name based and replace them with reportID based ones if the report exists, if the report doesn't exists and the user is not a member of the policy we will remove the mention and make it plain text, the details can be found here.
