tests: always access the mercurial repo through `helpers-testrepo.sh`
In some contexts the mercurial repo needs to be accessed through system hg.
That's what `helpers-testrepo.sh` enforces, but some tests incorrectly
use the mercurial repo without going through that script.
This patch fixes those tests.
{
// Enforcing
"eqeqeq" : true, // true: Require triple equals (===) for comparison

"nonbsp" : true, // true: Prohibit "non-breaking whitespace" characters.
"undef" : true, // true: Require all non-global variables to be declared (prevents global leaks)
