tooltips: Remove unnecessary checks for message action buttons in tippy.

We handled tooltips for failed message action buttons separately
through our default tippy-zulip-tooltip class because of
a diffrent html structure for these buttons. But as we refactored
html for those buttons to have same structure as for other buttons
in message action this extra check is no more needed.
