When we are trying to set the quantity on a mobile device, we get
a traceback saying that we cannot call the 'find' function on the
elements returned by '_get_records'.
This '_get_records' function returns a 'Collection' when called on a tree
view and an 'Array' when called on a kanban view. When we are working
on a mobile device, most of the one2many are displayed as kanban.
The thing is when we work with the object returned by '_get_records' we
call a 'find' method on it, which is implemented by Odoo's Collection class.
So when we call 'find' on an 'Array' we actually call 'Array.prototype.find' which
is implemented on most desktop browser and on some mobile browser [1]. This is what
caused the traceback on Chrome in Android.
To fix this issue, we enforce '_get_records' to always return an 'Array' and we ensure
that, when working on this 'Array', we use '_.find'.
