"Unknown entry URL" when building Launchpad

[Jonathan Lange]

When I build Launchpad using "make schema", I get many many "Unknown entry URL" warnings. It's not clear what to do about them, or why they are a problem. If they are a problem, we should fix them. If they are not, we should hide the warnings.

$ make schema

lp:~allenap/launchpad/no-one-cares-about-unknown-entry-urls has
silenced these warnings. We've been seeing them for maybe 2 years or
more. We should still do something about them - this bug is still
valid - but the warnings are not having any effect except making
builds very noisy.
