[BUGFIX] Do not reset items per page on search

Due to the previously used pagination, the
"items per page" option has been reset when
searching in the record list.

However, since the "new" pagination is
able to handle such filtered list, resetting
the "items per page" option is no longer
necessary and therefore makes lists with
a lot of matched items usable again.
