Fix/message deletion issues (#1697)

* SES-2810 - Removing the screenshot privacy toggle

* SES-2813 - clickable only when there is a 'follow settings'

* SES-2815 - proper icon and spacing for deleted messages

* Simplified deletion dialog to be reused for note to self and the rest as only the labels change

* SES-2819 - Do not show a reaction on a deleted message

* Fixing up deletion details

Message view hides reactions completely if the message is marked as deleted
All  messages can now show the 'Delete' long press option
Community messages should be removed completely not marked as deleted

* Revert "SES-2819 - Do not show a reaction on a deleted message"

This reverts commit 711e31a43a.

* Avoiding adding reactions if the message is marked as deleted

* Removing uneeded icon

* Deletion handled by VM so menu item is always visible

* SES-2811 - Do not attempt to send a failed message marked as deleted

* SES-2818 - Making sure we set the lastMessage in a thread properly, without using 'marked as deleted' messages

* SES-2464 - changed the behaviour to finish the convo activity but instead refresh the sarch on resume

* removing log
