Title: XD-1771 TwitterSearchTest now tests in append mode

Since the updates to TwitterSearch it returns multiple messages during the duration of the test.
Before we expected only one result/message now we get an indeterminate amount. Thus the
assertReceived was removed and the file sink that captures the results is now in append mode.
