[IMP] mail: add show more button on partner suggestion.

When sending a message from chatter, a list of suggested partners appears
on the top of the text area. With the previous commit,
cc will be added to this list. This commit adds a show more/show less
button in case there is more than 3 suggested recipients to display.
