[FAB-5446] Fix orderer metadata local test

The orderer metadata test only works if the development environment is
setup to set common.Version, because if this is not set, the version is
returned as "development version" and compared to the unset empty
string.

This is very annoying when trying to do development locally as this test
always fails.

This CR simply overrides the common.Version value for the purpose of
testing this package.
