remote_http_header's value in Junction set

[djorgen-ibm]

In the set function for junctions, on line 554, it is replacing '_' with '-' on the returned remote_http_header value from existing junction. On line 548, if current value for remote_http_header is "all", then it changes the value to ['iv_creds', 'iv_groups', 'iv_user']. Later on line 650 when it compares current junction values with existing values, it will always find differences since current value is ['iv_creds', 'iv_groups', 'iv_user'] and existing value is ['iv-creds', 'iv-groups', 'iv-user'].
