* CLDC-3501: Remove unfinished LogCreator tests
seems unclear what the test looked to verify, an existing log cannot be created
* CLDC-3501: Remove charge not provided test
this was moved to a soft validation in #1359
* CLDC-3501: Remove some year dependencies on LettingsLogController tests
no need to store a json of a complete log, we can generate this dynamically
* CLDC-3501: Reinstate skipped setup test
add some new time helpers to do with crossover periods
* CLDC-3501: Reinstate skipped schemes test
Can be made non specific to the year
* CLDC-3501: Reinstate skipped managing org rake test
the log can never be completed as it is missing info
* CLDC-3501: Reinstate row parser completed test
no changes needed, it already passes
