Add some DB optimizations (#6249)

Browse source 
* Set a maximum journal size limit (WAL file size) of 25MB

The previous value was null, which meant unlimited growth. This can affect performance, since the WAL file performance as a cache will worsen the larger it is

* When scheduling the vacuum task, make sure the user has enough free disk storage, since vacuuming can duplicate the DB sizes in disk
