Subject: efl_ui_pager: set current page as -1 when pager is empty
X-Git-Tag: accepted/tizen/unified/20190201.061426~106
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=fb56ae269d7ee58dcdb8e850e74ea1c724d7f86a;p=platform%2Fupstream%2Fefl.git

efl_ui_pager: set current page as -1 when pager is empty

it makes more sense that the current page number is -1 when pager is empty
since numbering starts from 0 when pager actually contains pages.
this patch also fixes a bug in pack_begin function, in which
the current page is increased by 1.
