[Test] Wait for sendEvent to return before continuing functional test.

[kevinlind]

Description

Fix failures from AEPEdgeFunctionalTests.testSendEvent_edgeNetworkResponseContainsLocationHint_sendEventDoesNotIncludeExpiredLocationHint()

This test sends two Edge.sendEvent() calls with a sleep between the two calls. The first sendEvent() will receive a location hint value with a 1 second timeout and the second sendEvent() is expected to not include the location hint as it expired. The test is failing because the second Edge.sendEvent() call contains the location hint when it is expected not to.

Looking at the logs it appears the execution of the first sendEvent() may take a second or so to complete, however the test thread is paused immediately after the api call. It appears the test thread is waking before the location hint expires because the sendEvent() call is taking longer than expected.

Fix by adding a completion callback closure to the first sendEvent() call so the test thread sleep does not start until after the first sendEvent() call completes.
