When no ridefiles are available (new cyclist) or the last ridefile is deleted the current ride will be null. In addition the ride importer deletes the memory for a ride imported to ensure VM is not exhausted on large imports. This patch fixes a whole host of null errors across the codebase. They were identified by creating a new cyclist, executing every menu option and tab/chart and then importing a file choosing everything and then deleting the file and choosing every option again. This negative testing should be performed before every stable release since it has identified at least 6 bugs which are almost certainly present in the current V2 code.
