fix: Prevent Deep Link Activation on Orientation Change

Previously, the deep link was inadvertently activated when the
fragment was recreated during an orientation change. This occurred
because the screen name value was unnecessarily re-fetched from the
fragment's arguments. To resolve this issue, we now set the argument
to null, ensuring that deep link activation no longer occurs during
orientation changes.

Fixes: LEARNER-9659
