Mobile / Fix expanded column not being scrolled into view

[adjogima]

It's an iOS-only bug where navigating to a board would often fail to bring the expanded column centered into view.
Safari seems to have trouble honoring the scrollIntoView call, especially in the web views.

• Start from the home screen.
• Navigate to a board from the main menu
• The expanded column is not properly scrolled and centered into view.
• Pull to refresh fixes it.

I've played with disabling view transitions in the apps, adding a delay before triggering a scroll, implementing a custom scrollColumnIntoView function for this controller but nothing worked reliably.

What seems to work reliably is switching from smooth scrolling to instant in the apps.

@adjogima the change looks good to me. Does it feel ok when switching between columns now (after the board has loaded) that we don't have smooth scrolling?

@jayohms I went back and changed it to "instant" when restoring the previously expanded column but "smooth" when switching between columns.

Looks good, thanks.
