[FIX] Generate missing XML only analysis files

First commit fixes a bug that prevented analysis files to be generated for modules with only changes in the set of XML ids (no changes in the database scheme).

The second commit adds these files, and rehashes the contents of the general analysis file containing information on dropped modules. Should not affect the work so far, or cause a lot of work anyway. Now, the l10n_es analysis is included, but again, this is still based on Odoo git of 3rd of June, without the latest refactoring by Pedro. Once this is merged, I can merge upstream Odoo and refresh all modules with the small number of recent, actual changes.
