fixed the JIRA issue: https://wso2.org/jira/browse/REGISTRY-2266

LC status column is getting removed when move to next page(paginating) in wsdl list page, as well as other artifact lists which involves, list_content.jsp file.
This was due to not recognizing that for each page (w.r.t pagination) the array size is always 15.
Earlier code has appended number of elemnts in the next page to 15. So, the for loop was incorrect.
The fix now iterates from 0 to number of elemnts (wsdls/schemas etc) in each page.
