[evolution-ews] Handle negative value for GUri's port

[Milan Crha <mcrha src gnome org>]

commit e9dc93c92beac8d9565a72ae4a0d00cf226c0638
Author: Milan Crha <mcrha redhat com>

    Handle negative value for GUri's port
    
    GUri uses -1 for 'port not set', but the code uses unsigned 16-bit integer,
    which makes the -1 an out of bounds value.
