Error in ltest or test-runner

[Bill T. Ota]

Note: Also created this ticket in the test runner project: lfe-rebar3/rebar3_lfe_ltest#2

When running the unit tests for the kanin project (see https://github.com/lfex/kanin/blob/master/test/unit-kanin-uri-tests.lfe), an error arises (unspecified ... looks like an undef of some sort). When run with rebar3, this error does not arise.

$ rebar3 as test lfe test -t unit
