Data Migration Tab Loading Fix Hook

Description
This hook fixes data migration tab loading issue. This is a JSP Hook for Liferay Portal 6.1.20EE.
If you have many files in document library of Liferay portal, this problem will occur. Data migration tab will not get loaded. Each uploaded/updated file creates entries to DLFileEntry and DLFileVersion tables in database.
When we load data migration tab in Control Panel > Server Administration > Data Migration, Liferay tries to get all the ConvertProcess types which can be used to migrate data. One of which is com.liferay.portal.convert.ConvertDocumentLibraryExtraSettings for which the query below runs. This query takes a lot of time to complete and depends on number of rows in both tables.
Usually the result of the query is zero and the method call convertProcess.isEnabled() returns false. And if it is false, ConvertDocumentLibraryExtraSettings is not going to appear in the dropdown which lists all available conversion process. In this case, it should be safe to use this hook.
