[FIX] mail: prevent message separator for new conversations

Before this commit:

When a new conversation is initiated, the 'new messages' separator is displayed.
This looks a bit weird as there is no history of conversation and thus no older
messages from which new messages should be separated.

After this commit:

The 'new messages' separator will not be displayed in new conversations.
