Subject: [PATCH] Avoid to call mail constructor (openConnection is an
 expensive operation) when client-side ask for vacationNotice. -Check if
 there's no vacation cached then create mail object (try openConnection) and
 ask for vacation -Add account_lid to cached vacations to distinguished them
 in case if the mail account was a shared profile
