ActiveInstallsIT#verifyActiveInstalls is flickering

ActiveInstallsIT#verifyActiveInstalls is flickering with following stacktrace:

org.junit.ComparisonFailure: expected:<[ActiveInstal]ls> but was:<[Pane]ls>
	at org.junit.Assert.assertEquals(Assert.java:117)
	at org.junit.Assert.assertEquals(Assert.java:146)
	at org.xwiki.activeinstalls.test.ui.ActiveInstallsIT.verifyActiveInstalls(ActiveInstallsIT.java:79)

This flicker behaviour happened during a slow CI occurence, but IMO it's related to a missing wait for applicationPanel.clickApplication("Active Installs"); basically the click is performed on the Panel application, but it seems like there's no real wait for the new page to load which could cause this kind of error.
