Don't include potentially sensitive window titles in logs

Browse Source 
For various error and warning messages, mutter includes a description of
the window, and that description includes a snippet of the title of the
window. Those snippets find their way into system logs, which then means
they can potentially find their way into bug reports and similar. Remove
the window title information to eliminate this potential privacy issue.
