mobile: fix dive detail scrolling

When using the current version of Subsurface-mobile, you cannot scroll
the dive details (i.e. you cannot see the bottom of the dive
information, depending on the size of your screen), nor can you scroll
the notes editor.

I'm not sure how I didn't stumble across this earlier, but a git bisect
appears to pinpoint commit a39f0e2891 ("Mobile: Fix QML Warnings.")
which is quite old.

Partially reverting this seems sufficient to get scrolling for the dive
details and dive notes edit working again.
