Bug Description

[Impact]

If the screen is locked, launcher/panel edge barriers at the moment are active.

[Test Case]

In a multi-monitor environment, lock the screen and move the mouse between monitors. There should be no "sticky" edge between the monitors.

[Regression Potential]

Code in the paths that handle the edge barriers was changed. Potentially this could impact the reveal of a hidden Launcher if there were errors introduced in these code paths.

[Other Info]

The fix for Ubuntu 14.04 LTS was cherry picked from the Ubuntu "Vivid Vervet" dev release where it has been in production use for some time.
