Connection CSV Import: Bug with "(attribute)" and "(parameter)" Suffixes

The example provided at /import/connection/file-format-help fails to import the attribute "guacd-encryption" correctly.

This can be reproduced with a CSV file like this:

name,protocol,username,password,hostname,group,users,groups,guacd-encryption (attribute)
importedconnection,rdp,bob,pass2,conn2.web.com,ROOT,guac user 1,,ssl

This seems to be the case with all values where the header contains "(attribute)" or "(parameter)" Suffixes.
