unattended-upgrades: call_adjusted() raises NoAllowedOriginError when marking packages to upgrade/install fails

[errors.ubuntu.com bug bridge]

[Impact]

 * Unattended-upgrades may when it can't find a solution for installing a package when all the candidates are from not allowed origins.
 * The fix is just not marking those packages to install without raising an error.

[Test Case]

 * Observe the error not being reported against fixed versions.

[Regression Potential]

 * The fix is not raising the error, but marking no package to install. As a regression u-u may miss some unupgradable packages, but in the callers this case is already handled.

[Original Bug Text]

The Ubuntu Error Tracker has been receiving reports about a problem regarding unattended-upgrades. This problem was most recently seen with package version 1.10ubuntu3, the problem page at https://errors.ubuntu.com/problem/dbb18e4c8f3777ec91c18aefd3a429f661227655 contains more details, including versions of packages affected, stacktrace or traceback, and individual crash reports.

The error is is falsely reported against the fixed version, too, with a stack trace from the unfixed version. This happens when reporting a crash occurred before upgrading the package. The error report is generated listing the upgraded package's version.
