Improve QueryGrid synchronization

Rationale

QueryGrid.clearAllSelections has been failing intermittently. Waiting for the grid to be loaded before the action seems to do the trick.

java.lang.AssertionError: Did not successfully clear all the selected items in the grid.

Some tooltip tests have been triggering (or failing to trigger) tooltips because the mouse is left in an inconvenient spot after a previous step. Moving the mouse to the corner of the page before navigations should prevent some of these accidental interactions.
