edje_calc: Fix invalid parameters during first calc

In particular, ellipsis is -1 by default in Evas, but at this
point (first layout calc), the parameters used for recalc are
incomplete and ellipsis would then be 0 by default (calloc).

As a consequence, Edje will call ellipsis_set(0) enabling
ellipsis even on objects that force "ellipsis: -1".

Solution: set all the parameters before entering text/tb calc.

I believe the other changes are only color and image padding
and should not affect recalc_single.
