Changed  warning message to match pacman's warning message

Changed warning message when package is on IgnorePkg and there's an upgrade available.

Before:

warning: phpstorm-eap 131.235-1: ignoring package upgrade (131.235-1 => 131.332-1)

After:

warning: phpstorm-eap: ignoring package upgrade (131.235-1 => 131.332-1)

This way we mimic the original pacman's warning message:

warning: nginx: ignoring package upgrade (1.2.9-1 => 1.4.2-4)
