Default parameters in computed properties compiles incorrectly

[coulson84]

Not sure if this is considered an anti-pattern in terms of using svelte but I had setup a computed property using a default value and it did not compile to what I was expecting it to

given a computed object as below

computed: {
  someProperty: (val1, val2 = 'defaulted') => val1 + val2 
}

Then applyComputations for the component has the following code present

if ( ( 'val1' in newState && typeof state.val1 === 'object' || state.val1!== oldState.val1) || ( 'undefined' in newState && typeof state.undefined === 'object' || state.undefined !== oldState.undefined ) ) {
		state.someProperty = newState.someProperty = template.computed.someProperty( state.val1, state.undefined );
	}

Thanks
