Logs; removed obsoleted property "BranchPk"

In version 2.3.0 the property "BranchPk" of finLogRO was obsoleted. This property has now been removed.

This means the database query that retrieves Logs can be optimised for better performance.

Note, in addition the following functions have been obsoleted in the finLogs collection:

LoadAccountAdHoc
LoadAccountAdHocPk
LoadClientAdHoc
LoadClientAdHocPk
LoadUserAdHoc
LoadUserAdHocPk
