Bug in config.py type checking

[awknaust]

The old (1.37) compared types properly but in development, isinstance is being misused. This resulted in a exceptions when a new config option was being added (maybe when moving the preferences dialog)

Using isinstance is the correct usage to compare types, I just messed up the implementation here.

A test needs add to test_config to replicate this issue and ensure it is fixed.

Do you have the exception trace or how to replicate?

[awknaust]

This is an example traceback. I wrote a short test case to cover this scenario

Traceback (most recent call last):
  File "/home/awknaust/deluge/deluge/ui/gtkui/preferences.py", line 831, in on_pref_dialog_configure_event
    self.gtkui_config["pref_dialog_width"] = event.width
  File "/home/awknaust/deluge/deluge/config.py", line 148, in __setitem__
    return self.set_item(key, value)
  File "/home/awknaust/deluge/deluge/config.py", line 189, in set_item
    value = oldtype(value)
TypeError: cannot create 'NoneType' instances

Thanks, I've added to develop your test [3b950094] and fixed the issue [11c6e387].
