Allow opening activity to specify orientation.

An activity's window is initially not visible. This means it is not
accounted for until it becomes visible, which means requested
orientations will not be honored until after onCreate.

This changelist removes the visibility check previously used determining
the orientation.

This changelist also addresses an issue where an ActivityRecord member
variable tracking the last configuration sent was not being initially
updated.
