lp.services.worlddata.model.language unusable unless lp.services.worlddata.model.spokenin imported first

[Jonathan Lange]

I'm landing a branch that removes all of the glob imports from canonical.launchpad.database.__init__. When running the tests, I get errors like this.

File "lib/lp/services/worlddata/tests/../doc/language.txt", line 290, in language.txt
Failed example:
   print [country.name for country in es.countries]
Exception raised:

   PropertyPathError: Path 'SpokenIn.language' matches no known property.

These go away when I add:
    from lp.services.worlddata.model.spokenin import SpokenIn

to the top of lib/lp/services/worlddata/model/language.py. I don't really know why.

For the moment, I'm leaving that line in there with a XXX comment.
