Compare attribute's resolved link with default value

If an attribute is a link, when checking whether its value is
the default value, only the resolved value should be compared
with the default one. Otherwise, the attribute's "isDefault"
property will always evaluate to True, even when a non-default
link has been provided.

This issue was especially evident with input File attributes,
for which the default value is generally '' (empty string); if a
link was set as a value (thus non-empty), its unresolved value
would still be '', thus setting the "isDefault" property to True.
