Class 'is-selected' doesn't get added to selected options when multi=true

[a6hi5h3k]

Upon passing your own method in props for filterOptions to also show selected options in Dropdown for MultiSelect box, the class is-selected doesn't gets added to the option elements.
Following line in buildMenu() looks to be rogue which could be fixed.

var isSelected = this.state.value === op.value;

The value in state is a comma-separted string of values here, which will always fail this check.
