cacheurl_qstring.conf file is not generated when qstringIgnore=1 and location profile parameter is missing for edge/mid cache

cacheurl_qstring.conf file is not generated when qstringIgnore=1 and location profile parameter for config file cacheurl_qstring.config is missing for edge/mid cache profile. This is a issue because remap.config references this non-existent file.

e.g. map http://edge-cache.http-ds.mycdn.somedomain.com/ http://origin-server.somedomain.com/ @plugin=header_rewrite.so @pparam=dscp/set_dscp_0.config @plugin=cacheurl.so @pparam=cacheurl_qstring.config

The workaround is to add location parameter for cacheurl_qstring.config config file to the edge/mid cache profile.
