* Fall back, if table logon_db_version not exist, it will be automaticall created. The logon_db_version will be the version it was original implemented (hardcoded in this case).
* Logonserver checks the db version based on the hardcoded value and the entry in logon_db_version.
NOTE: All update files are required, we should set the required db versions based on the latest file in the update folder instead of a manually set hardcoded value. (CMake?)
