[bugfix] Line update bugfix

[swed]

Hello !

There is actually a bug when updating a line from the schedule list window :
- Select a line and click "update line" button
- Update the line, but keep same stops count
- Close the line edit window
Back to the schedule list window, line is not updated, old stops are still displayed.

Here is a bugfix, hope that'll help.

Bye !
