[FIX] web: selection field with value 0

The server doesn't make a distinction between an unset selection
field, and a value 0 (integer). So when 0 is a valid key for the
field, the server returns false as value if the field is unset, or
if its value is 0, which is not really convenient.

As a consequence, when the value is 0, it appears as unset in the
interface. To circumvent this, we automatically converts false
value of selection fields to 0, if 0 is a key of the selection.
