fix test failures introduced in r50494

This commit changes some of the `require` tests to run *without*
rubygems enabled.  Those particular tests were removing rubygems from
$LOAD_PATH.  These tests assert that a `LoadError` is raised.
Unfortunately, since RubyGems was enabled by default and was not fully
loaded, the load error actually originated from RubyGems, *not* from
where the tests intended.
