Zbigniew Jędrzejewski-Szmek 7559b2da10 test-user-util: skip most tests for nobody if synthentization is off 
When synthetisation is turned off, there's just too many ways those tests can
go wrong. We are not interested in verifying that the db on disk is correct,
let's just skip all checks.

In the first version of this patch, I recorded if we detected a mismatch during
configuration and only skipped tests in that case, but actually it is possible
to change the host configuration between our configuration phase and running
of the tests. It's just more robust to skip always. (This is particularly true
if tests are installed.)
