MDL-64267 core_message: Moved contact-request to dont cause scrollbar

The contact-request-sent-message-container was outside of the
conversation body and caused multiple overflows and thus multiple
scrollbars. Moving it inside does not have an effect on the layout
except one scrollbar is enough now.
