Verify that the classpath for Geode always has the geode-core jar first in the list of paths.
On entry to the test there may (depending test platform) be a version of geode-core-*.jar on
the system classpath, but at an unknown position in the list. To make the test deterministic, a
dummy geode-core-*.jar path is inserted in the system classpath at a known, but not the first,
position.
