Delete operations override 0 (yank register)

[jojojames]

Noticed evil-cp-delete-char-or-splice is calling evil-cp--yank which eventually checks

  (when evil-was-yanked-without-register
    (evil-set-register ?0 text)) ; "0 register contains last yanked text

where evil-was-yanked-without-register is t (for some reason).

With evil-cleverparens disabled, on a text of

a
b

yy on line a -> :reg -> a is in the 0 register
dd on line b -> :reg -> a is in the 0 register, b is in the 1 register (and others) (expected)

With evil-cleverparens enabled, with the same text
yy on line a -> :reg -> a is in the 0 register
dd on line b -> : reg -> b has replaced a in the 0 register (unexpected)
