New install impossible on Trac 1.0beta1

[Benjamin Lau]

I was trying to evaluate test manager for trac on a fresh install of 1.0beta1 and ran into the following error:

19:53:36 Trac[env] ERROR: Exception caught while checking for upgrade:

Looking into this it looks like a common problem that many plug-ins have been having during the 1.0 release cycle. #10230 #9742 Looking at the solution used in #10230 I've produced a patch for test manager that at least allows it to install. I'm not sure if this is the right way to deal with this since it looks like #9742 uses a slightly more complex approach.

See comment on #10293.
