fix: allow passing MFA tickets when changing an account's email address (#179)

* fix: allow passing MFA tickets when changing an account's email address

This commit adds an `MFATicket` parameter to the `AccountCollection.changeEmail`, which the backend mandates when the account has MFA enabled. The client still has to manually check whether passing a ticket is necessary by using `MFA.authenticatorEnabled`.
