ENT-5886 Parameterised queries in DBCheckpointStorage (#6768)
Direct SQL was causing issues with the saving of instants not
maintaining their timezones properly.

Changing to parameterised queries fixed this issue.

Also changed other queries to do the same, since it is good practice to
query in this way.
