fix(webmail): a barra lateral mostra so o que esta por ler

Mostrava tambem o tamanho de cada pasta. Sao numeros que nao mudam e
que ninguem esta a espera: enchiam a barra sem dizer nada de util.
Agora aparece um numero apenas onde ha correio por ler, e nada nas
restantes.

Consequencia a saber: Rascunhos nunca tem mensagens por ler - nada
marca um rascunho como lido - portanto passa a nao ter numero nenhum.
Quem quiser saber quantos rascunhos tem, ve-o no cabecalho da pasta.

O tamanho continua no tooltip do link, e o cabecalho da lista continua
a dize-lo por extenso, portanto a informacao nao se perdeu - deixou
apenas de estar sempre no campo de visao.
