Improve error message if adding neurodata types of the wrong types as property values

[ehennestad]

Motivation

Throw more precise error message if trying to set a Neurodata type which is incorrect type

How to test the behavior?

Before

not_a_device = types.core.OpticalChannel('description', 'test_channel');
electrodeGroup = types.core.ElectrodeGroup(...
    'description', 'test_group', ...
    'device', not_a_device); %#ok<NASGU>
        
Error using assert
Value of type `types.core.OpticalChannel` cannot be converted to type `types.core.Device`:
  value is not instance of type types.core.Device. Got type types.core.OpticalChannel instead

After

not_a_device = types.core.OpticalChannel('description', 'test_channel');
electrodeGroup = types.core.ElectrodeGroup(...
    'description', 'test_group', ...
    'device', not_a_device); %#ok<NASGU>
        
Error using assert
Expected value for `device` to be of type `types.core.Device`. Instead it was `types.core.OpticalChannel`

Suggested change

	tf = false;
	if startsWith(typeName, 'types.') && ~startsWith(typeName, 'types.untyped')
	tf = true;
	tf = startsWith(typeName, 'types.') && ~startsWith(typeName, 'types.untyped');

[ehennestad]

Changed this to check that the provided string is a class which inherits from types.untyped.MetaClass.

That previous implementation would return true for any string starting with typed.<something>
