These arguments were only used by options_validate, and are now
ignored even there.

Since each of these tests only applies to testing networks, put them
all into a single block that checks for testing networks.

(I recommend reviewing with the "diff -b" option, since the change
is mostly indentation.)

It can just look at what the defaults are.

Closes ticket 32185.

This pleases practracker.

Two things needed to be changed.  First, we used to set quiet_level
to the default (QUIET_NONE) when running tests, since we would not
call anything that acted based upon it.  But since we sometimes call
options_init_logs(), we need to pre-set quiet_level to QUIET_SILENT
in the logs so that we don't add the default logs.  This did not
cause test failure: just unwanted logs.

Second, we had a test that checked whether options_validate was
messing with options->Logs correctly.  Since options_validate no
longer messes with the logs, we no longer want a test for this.
