set accessibilityValue to text value if there is no error

when deleting text, the accessibilityValue is not set to the value of
the text. For example

Erro => Erro
Error => Error, the new text is Error (announcing error)
Erro => Erro
Err => nothing (should be Err)
Er => nothing (should be Er)
E => nothing (should be E)

when we move focus out/back, the announcement is Erro, even if the
text is (E, Er or Err)

after the fix

Erro => Erro
Error => Error, the new text is Error (announcing error)
Erro => Erro
Err => Err
Er => Er
E => E
