core (memory/disco): fixed types of disco extensions:
typeCheck() is not automatically called on reception by Wokkel, as a result extensions
fields values may be strings instead of the field type. TypeCheck is now explicitly
called in memory.disco to avoid that. It is not called immediately on reception as the
string value is needed to calculate the capability hash
