[BUGFIX] Fix "undefined array key" issues in LiveSearch's page jump

This patch adds a few null-coalesce conditions in the LiveSearch in case
a field not defined in TCA (in most cases uid and pid) is queried, which
is the case when using the "page jump" feature.

As a drive-by, these issues are fixed as well:
* Pass `$queryBuilder` as a reference, which makes no sense for objects
* Adding SQL constraints twice
