Keep CommitTs module in sync in standby and master

Browse Source 
We allow this module to be turned off on restarts, so a restart time
check is enough to activate or deactivate the module; however, if there
is a standby replaying WAL emitted from a master which is restarted, but
the standby isn't, the state in the standby becomes inconsistent and can
easily be crashed.

Fix by activating and deactivating the module during WAL replay on
parameter change as well as on system start.
