    online-accounts: Fix parameter parsing
    
    The Online Accounts panel supports two commands: 'add'
    and 'show-account'. The 'add' command must receive an
    additional parameter, the 'provider' name, and an
    optional 'preseed' parameter.
    
    In the past, Settings would just push all the parameters
    to a GVariant and pass to the panels. Now, however, it
    skips the first one, making the parameter parsing code
    in Online Accounts panel wrong.
    
    This patch fix that by refactoring add_account() code,
    and fixing the GVariant parameter parsing.
