fix regressions after save modal changes of not storing time and variables per default

Fix problem with adhoc variable filters not handled.
Fix problem with saving variables and time per default when saving a
dashboard as/first time.
Fix updating dashboard model after save with saving time/variables
enabled so that next time you save you won't get checkboxes for save
time/variables unless any values changed.
Tests validating correctness if time/variable values has changed.
