minor test suite cleanup, revive old test (#8497)

There are two tests in other.tcl that were dependant of the sha1 package
import which meant that they didn't usually run.
The reason it was like that was that prior to the creation of DEBUG
DIGEST, the test suite used to have an equivalent function, but that's
no longer the case and this dependency isn't needed.

The other change is to revert config changes done by the test before the
test suite continues. can be useful if using `--host` to run multiple
units against the same server
