evas/async_render: skip early if text_props with no glyphs

This is intended to preserve old behavior now that we have
evas_common_font_draw_cb() to handle both sync and async callbacks.
However, we need to check where why we end up with no glyphs in a
text_props even after calling evas_common_font_draw_prepare().
