Disable morph logging during TestMain (#30948)

* rm "No TEST_DATABASE... override" log message

Let's only log if this value is actually overridden.

* rm "(Created|Dropped) temporary database" message

* only log "Pinging SQL" on subsequent attempts

* disable morph logging from TestMain

* Fix style issues in store test files

- Add missing parameter to migrate() function calls in tests
- Remove unused log function in settings.go
- Fix formatting with go fmt

* within sqlstore, use "enable" vs "disable" for clarity

* remove trailing newline from morph logs
