Subject: [PATCH] Fix pingback on non-MySQL

MySQL has its own implementation of upsert(), but the others rely on
$uniqueIndexes being a field list, not a field/value associative array.
The previous code generated an SQL error when checking for existing
values.

Bug: T200864
Change-Id: Ifb56f7f350fbb84144bc6f5a1dd76939816338a6
(cherry picked from commit ba54f7f90dce0e06ff3c4ad1ec141362f10be9a9)
