edje: fix text set/get issue without edje calculation

Summary:
Some changes broke really basical function behavior of text.
I couldn't get text from an edje object which I just set to the given edje object.
In the past code, edje called recalc function before trying to get text.
So, this patch bring that code to fix this issue.
@fix

Test Plan: Included. Run "make check"
