Student's list search index does not reset when updating search filters

[Prater-12]

When the search phrase is changed, the student's list page displays the first set of results for the given filters. However, this fact is not reflected in the page's index, since the first result index remains the same as before the search was made.

Because of this, going to the next or previous page will calculate first index based of the page the user was before the search was made.
