fix: Avoid error message display on page display when session timeout -

MEED-7171 - Meeds-io/meeds#2249 (#510)

Prior to this change, when displaying a page while the session timed
out, an alert message is displayed. This change ensures to display the
alert message only when the user makes an action on Kudos module and not
on loading time.
