Trailsave plugin: remove second trailing line 

The intention was that there should be one empty line left at the end of the file, but the GtkSourceBuffer adds it's own empty line if the implicit_trailing_newline property is true (currently the default behavior in xed), which means we usually end up with 2 lines instead of one. This would change the behavior so that we always end up with no more than one line at the end of the file.
