[Utils] Duplicate tpl-name indices when creting rev-tpl-idx and page-tpl-idx at the same tim

[daxenberger]

Originally reported on Google Code with ID 101

The WikipediaTemplateInfoGenerator can generate template indices for revisions and pages
at the same time.
However, the WikipediaTemplateInfoDumpWritercreates separate tpl-name-ids for the page
and revision index - resulting in duplicate entries in the tpl-name-tpl-id table.

Currently, the option to create both indices at the same time has been disables.
A fixme-marker has been created in WikipediaTemplateInfoDumpWriter.

Workaround: Create one index, import into db, create other index, import into db.
