pager16: resize on desktop bug fix

Summary:
pager16 is not properly resized when it is a desktop gadget.

Case 1. In move/resize mode, shrink is impossible since all items' min has been set by setting table options on resizing.
-> Do not set table options in _pager_resize().

Case 2. After log-in, if we open new window, pager has been get into move/resize mode.
frame resize was ignored, since it's invoked in the middle of resizing.
The detail is:
1) gadcon's frame is resizing
2) the table is resized
3) _pager_resize() -> e_gadcon_client_aspect_set() -> _gadman_gadget_size_hints_cb() -> try to resize frame
4) since frame is in the middle of resizing, the resize request has been ignored. (at start, since the initial size was 0, 0, pager get into move/resize mode)
-> Defer aspect setting.
