[FEATURE] Mock EmailServiceTest

[gstuer]

Circumstances
The EmailServiceTest class sends real emails with a JavaMailer instance. Therefore, testing the sent Strings is impossible.

Recommended Solution
Mock the JavaMailer and return the String instead of delivering it to the SMTP server.

Alternatives

• Keeping the test as "real" as possible and using it only if testing of email functionality is required. So the test class have to stay ignored by jUnit.
• Adding a filter to the noreply gmail account and use it for fetching all mails. They should be grouped within a folder to make bulk deletion possible. (-> Better solution than mocking?)

Mocking the JavaMailer sounds like the simplest solution.
