 When you test a connection and it fails an error message is displayed in
 the text box next to the test button. When changing settings and pressing
 test again, the same error message keeps displaying until the  new test
 returns either true or an error message. If the same error message is
 displayed again then you are unsure if the test has run at all.
 When pressing the test connection button the text box should be cleared as
 the first thing, before running the actual test.
