[6.1 trunk] module uninstall leaves residual data

[Bogdan Stanciu]

Hello,

while doing a db update, I got some warnings, like these ones (there are more, actually):
2012-02-15 13:31:51,431 19158 WARNING bs_02 openerp.modules.loading: Model account.asset.method is declared but cannot be loaded! (Perhaps a module was partially removed or renamed)
2012-02-15 13:31:51,479 19158 WARNING bs_02 openerp.modules.loading: Model res.better.zip is declared but cannot be loaded! (Perhaps a module was partially removed or renamed)
2012-02-15 13:31:51,636 19158 WARNING bs_02 openerp.modules.loading: Model thunderbird.installer is declared but cannot be loaded! (Perhaps a module was partially removed or renamed)
2012-02-15 13:31:51,727 19158 WARNING bs_02 openerp.modules.loading: Model stock.ups is declared but cannot be loaded! (Perhaps a module was partially removed or renamed)
2012-02-15 13:31:52,003 19158 WARNING bs_02 openerp.modules.loading: Model account.coda is declared but cannot be loaded! (Perhaps a module was partially removed or renamed)

I know that uninstall is a 'beta' process (however since quite a while) and these are "just" warnings, however I think that some improvements could be made, as I noticed important amounts of data were left in:
* ir_model
* ir_model_data
* ir_model_fields

this bug might be related (not duplicate) with #657331 and #719252 and maybe others.

Regards,
Bogdan
