Can't correctly divert to a stitch using a parameter

This one's a little hard to explain, but the sample code should illustrate the issue.

```
<- goToStitch(-> knot)

=== goToStitch(-> divert)
<- knot.stitch2
<- divert.stitch2

=== knot

= stitch1
1!

= stitch2
2!
```

Expected output:
```
2!
2!
```

Actual output:

```
2!
1!
```

I believe this is caused by Ink diverting to the knot, and falling through to the first stitch, ignoring the request to jump to a stitch. If you add text before the first stitch, Ink will display this instead.
