When one `nsslapd-pluginarg` argument is missing in 7-bit plugin config configuration, DS crashes:

When one nsslapd-pluginarg argument is missing in 7-bit plugin config, DS doesn't crash. In the errors log: 

[26/Dec/2014:02:10:15 +0100] NS7bitAttr_Init - Invalid plugin arguments - missing "," separator argument
[26/Dec/2014:02:10:15 +0100] - Init function "NS7bitAttr_Init" for "7-bit check" plugin in library "libattr-unique-plugin" failed
[26/Dec/2014:02:10:15 +0100] - Unable to load plugin "cn=7-bit check,cn=plugins,cn=config"

Marking as VERIFIED
