Fix: Synchronize acknowledged werks to slave sites in distributed WATO setup

[sven-ruess]

General information

Acknowledged werks on master site are not synchronized to slave sites in distributed WATO setups.

Bug reports

All versions are affected by this issue, because synchronization is same on all editions. Create a distributed setup with master and slave. Do a login on slave site. Incompatible werks will be shown on help.

Proposed changes

If those werks are acknowledge on master site, they will also be handled on slave site the same way. If slave is reconfigured to be standalone, all is correct and on login on slave site those werks are not shown again.
