Bug#548404: epiphany-webkit: epiphany.gecko diversion is left after upgrade, then uninstall

[Mike Hommey]

Package: epiphany-webkit
Version: 2.28.0-3
Severity: normal

I upgraded epiphany, and it left the epiphany.gecko diversion around. Then
I uninstalled (and purged) the epiphany-webkit dummy package, and it was
still there.
