elementary/ctxpopup - correct position and size of ctxpopup

Dear all,

With ctxpopup, if it has many items and user uses -1 as parameter in set direction priority function,
the ctxpopup position and size are calculated incorrectly.
Ex:
elm_ctxpopup_direction_priority_set(ctxpopup, ELM_CTXPOPUP_DIRECTION_DOWN, ELM_CTXPOPUP_DIRECTION_UP, -1, -1);

I would like to send a small patch to fix this issue.
Please take a look on it.

Thanks & Regards,
Thiep Ha
