Bug: updating an ics does not change event name

Hi,

I imported a custom .ics file from a link, then noticed the X-WR-CALNAME entry was wrong (as in, the title of the entire file).

I can refresh the ics all I want, it doesn't change the title of the thing anymore. (Also, as others have noted, I can't delete my own imported .ics anymore, which I would like to do, for older events I added)
