Summary:
If an interface controller has a table and you specify more than one row in the storyboard, you cannot use the [WKInterfaceTable -setRowTypes:] method in [WKInterfaceController -willActivate] to create rows with more than one type.

Steps to Reproduce:
- Create a new iPhone project.
- Create a WatchKit app target.
- In InterfaceController.m, create two empty classes (@interface and @implementation declarations), Row1Controller and Row2Controller.
- In InterfaceController.m, in the class extension, add the following line of code:
@property (nonatomic, weak) IBOutlet WKInterfaceTable *table;
- In InterfaceController.m, in the -willActivate: method, add the following two lines of code:
    NSArray *rowTypes = @[@"Row1", @"Row2"];
    [self.table setRowTypes:rowTypes];
- Add a table to the empty interface controller scene.
- Set the number of rows in the table to 2.
- Set the first row's class to Row1Controller and its identifier to Row1.
- Set the second row's class to Row2Controller and its identifier to Row2.
- Hook up the "table" outlet of the InterfaceController.
- Compile and run the Watch App scheme.

Expected Results:
Console output contains no errors:

Actual Results:
