Case when a stop point doesn't get deleted properly

[solita-sabinaf]

A bit rare to encounter but still, there is one scenario when stop point deletion doesn't go well. Steps to reproduce:

1. Open journey patterns' stop points form

2. Add a new stop point (just so that it's possible to delete one) and fill it with some value, the position in the sequence doesn't matter, just as long as there is one more stop point coming earlier with (important!) all the fields being empty and "pristine"

3. Delete the empty pristine stop point (any of the those) which is preceding the stop point that had some quay value entered

4. After "yes" was pressed in the previous step, the dialogue stays visible. In the background can be seen that now there are 2 stop points, so deletion took place

5. After pressing dialogue's "close" button, the stop point that initially had a quayRef value entered, no longer has the value visible (the stuff visible is the placeholder's default suggestion text). Clicking anywhere outside the quayRef field would result in the quayRef value being cleared away entirely
