Fix Exception when QueryCollector softLimit exceeded (#1702)

The other match() case is:
$query->connection->prepareBindings($query->bindings)

This method always returns an array.

Before this commit the match() case would return null, which is the wrong data type used downstream.
This resulted in Exception:

Debugbar exception: foreach() argument must be of type array|object, null given
