Title: Update testing dependency and use jc.ErrorIsNil

Replaced all occurrences of
c.Assert(err, gc.IsNil)
with
c.Assert(err, jc.ErrorIsNil)

Also replaced `c.Check` variants.

While I was making such a massive change, I also changed:
gc.Equals, true)
to
jc.IsTrue)

and
gc.Equals, false)
to
jc.IsFalse)
