Customer reported bug that running the command ./console core:purge-old-archive-data all didn't save DB space. They also had to run ./console database:optimize-archive-tables all afterwards.

Suggested steps:

• In the core:purge-old-archive-data console command, let's remove --force-optimize-tables option and always optimise tables
• in Db::optimizeTables let's remove the second parameter $force = false and always force optimise tables (the code already checks isOptimizeInnoDBSupported which should be enough) (not wanted actually)
