Did you try to delete the offending lists manually?
I suspect you may have something related to the list which is preventing it from deleting.
Try deleting the list manually.
I generally have a VS project for the site building pieces (site columns, content types, lists and libraries etc) (usually I refer to this as the “Base Project”) and then separate projects for event receivers and other things. Â
The “Base” project then deletes the entire site collection via a script and recreates it as I test my site columns and content types etc. Â This prevents problems like this.
