Ignoring validation for last poll answer input

last input field is only deleted if there are more than three input fields and the last one is empty

poll is validated only if the last input is empty, and the first three have been filled

Removed duplicate remove last answer.

Dont need to check that the last value is populated as we are ignoring last value
