We need to reset 'showsharedviews' and 'showsharedcollections' values
to 'By members of this group' for the default group home page because
they were wrongly modified.

We need to default the 'display shared pages' option to 'By anybody'
value=2 as this is the same rules as the before upgrade.

We can leave newly created groups to default page/collection display to
'By members of this group'.
