test: Extend the sleep time to allow save to work (#1142)

* Extend the sleep time to allow save to work

The sleep time should be increased to allow the save time to vary significantly from the variable savedTime so that any time different between the client and the server’s  clock is negligible compared to the sleep time.

* test: Extend the sleep time to allow save to work

* run linter

* Reapply sleep commit that was there first
