    evas textblock: fix a rendering issue.

    It's a rare case but a possible scenario that textblock is not updated
     properly in case of textblock rendering via proxy/map.

    If the textblock state turned out with an invisible state,
    its relayouting won't be up to date. But actually, it could be rendered
    by map/proxy. In that case textblock text layouting would be incorrect.

    Additionally, removed evas event freeze state there because map/proxy won't
    be drawn under the event freeze state always.

    @fix
