Last event item date is affected by cancelling an event dialog, causing a bug when moving the event around.

Hi, this is a great library that I stumble upon recently and I have been trying very hard to customise and fit your great work into my project.
I have discovered that there is one bug that seems to cause the last event end date to be changed to the start date of the event dialog's start date when the event dialog is cancelled.

I tried replicating the steps for the bug on your example app (https://clickermonkey.github.io/dayspan-vuetify/example/) and it always recreates the same issue.

Step 1: click on a date on the calendar and create an event. Save the event!

Step 2: click on a later date on the calendar and create an event, but press cancel instead.

Step 3: when you drag the saved event, the end date will be = to the cancelled event start date OR the days between the first saved event and the cancelled event.

new update: If the drag feature is disabled, the issue seems to be resolved.
this.$dayspan.features.drag = false;

Thanks for discovering this, I've seen this before but could never replicate it! Next version should have a fix.
