Change evil-paredit-delete from overriding evil-paredit-yank's behavior

For non-block types the old version used kill-region for actual deletion. Changed it to delete-region so that it doesn't override evil-paredit-yank that's called right before. The difference is easy to see by typing `yy` followed by `p` or `P` on indented code. The new version puts on new line like it does in vim.
