Optimize Azure pipeline (#17674)

* Only fetch single commit

* Hopefully fixes Nerdbank.GitVersioning.GitException: Shallow clone lacks the objects required to calculate version height. Use full clones or clones with a history at least as deep as the last version height resetting change.

* Do not checkout again

* More test pipeline

* Another attempt

* yet another attempt

* more attempts

* Revert "more attempts"

This reverts commit 5694d97ba620e90fdeea287936f58002f2a5ddba.

* Test without building backoffice and login explicitly

* Fix mem leak in integration tests

* Fixes sqlserver lock test
