[4.x] General code cleanup (#1278)

* Declare sensitive parameters as sensitive

... just so that they don't show up in logs

* Remove unnecessary null-coalescing

* Simplify return

* Merge isset() calls

* Inline return

* Use nullsafe operator

* Simplify if-else branches

* Use direct empty string comparison instead of strlen()

* Add missing type

* Change interface as events expect a TenantWithDatabase not just a Tenant

* Narrow typehint

* Remove redundant type casts

* Fix style with php-cs-fixer

* Fix typos

* Revert unwanted if-else simplification

* fix phpstan errors

* narrow type
