Editing Memberships Shows Incorrect Message

When you edit a membership there is an option to send a confirmation. By default this option is not checked. Though no email is sent CiviCRM was reporting that an email was sent when the box was not checked.

For example:
A confirmation and receipt has been sent to email@domain.com.

Nicolas reported to me there was an issue with the structure of the if statements that determined the message. Nicolas has patched and will submit a PR. This is the JIRA ticket to go with the PR.
