evm:automate:export rake task broken when EXPORT_AS contains domain substring

Issue

• When using EXPORT_AS with the evm:automate:export task, the domain file has swap_domain_name() run twice. When the EXPORT_AS domain is a substring of the source domain, this results in a broken export (zip file in this case). For example:

      216  04-13-2015 15:01   EXAMPLE/System/Request.class/winrm_cmd.yaml
      230  04-13-2015 15:01   EXAMPLE/System/Request.class/winrm_powershell.yaml
      158  04-13-2015 15:01   EXAMPLE/System/__namespace__.yaml
        0  04-13-2015 15:01   EXAMPLEEXAMPLE/
      176  04-13-2015 15:01   EXAMPLEEXAMPLE/__domain__.yaml

• The backtrace where it happens:
