Correct check for enabled expiration date

The default expiration date cannot be enforced if it is not enabled
in the first place. Hence, the check for whether a share has an expiration date
should not consider enforcements but only where the share expiry type is enabled.

For example : Using `this.config.isDefaultExpireDateEnabled` instead of
`this.config.isDefaultExpireDateEnforced` which can be verified by checking `isExpiryDateEnforced`.
