elementary_tests.exe: Scroller on Popup sometimes don't pop

[Coquinho]

Current behavior

Some times the popup opens in a little window, that can't even fit the Cancel
button creating a need of resizing the window to see it properly, when it does
open correctly it yields errors like:

ERR:edje ../src/lib/edje/edje_util.c:3998 _efl_canvas_layout_efl_layout_calc_calc_size_min() file C:/Users/coku/source/efl/prefix/share/elementary/themes/default.edj, group elm/notify/center/popup/default has a non-fixed part 'elm.swallow.content'. Adding 'fixed: 1 1;' to source EDC may help. Continuing discarding faulty part.
ERR:edje ../src/lib/edje/edje_util.c:3998 _efl_canvas_layout_efl_layout_calc_calc_size_min() file C:/Users/coku/source/efl/prefix/share/elementary/themes/default.edj, group elm/notify/center/popup/default has a non-fixed part 'elm.swallow.content'. Adding 'fixed: 1 1;' to source EDC may help. Continuing discarding faulty part.

Those errors are the same as in #433.

Expected behavior

Now errors at the terminal and popup windows should always open correctly:
showing text and button.

Steps to reproduce

1. Run elementary_tests.exe
2. Open Scroller on Popup
3. Press either Button 1/2
4. Note that if you can see the Cancel button your terminal should have the
   errors stated earlier, otherwise you will need to resize the window to see the
   popup correctly
