Fix titan-hadoop-1 regression

EmptyConfiguration's constructor has been broken under Hadoop since (I
think) the port from github.com/thinkaurelius/faunus's faunus05
branch.

Expand graph configuration option tests
Fix bug in ExpectedValueCheckingTx

EVCT calls getSlice with bounds [col, nextBiggerBuffer(col)), where
col is given by the caller.  This slice returns exact matches of col,
if present in the backend, but it can also return longer columns for
which col is a prefix.  This is a bug -- EVCT should be responsible
for ignoring columns which aren't an exact match of col provided by
the caller.

This manifested as a bug in
ThriftGraphCacheTest#testGraphConfiguration which actually had nothing
to do with db-cache.  The problem was that ECVT was considering both
values for "cache.db-cache" and "cache.db-cache-time" when attempting
to lock and check "cache.db-cache", causing a nonsensical
PermanentLockingException.

Fix graph config tests under BDB

The BDB edition of graph-config-option-mutability tests failed due to
a transaction held open during graph.shutdown(), which under BDB leads
to an exception and test failure.  Changed the affected tests to be
more careful with their transaction handling and the BDB test now
passes.
Tweak GroovyTestSupport for 0.5 compatibility

Also partially updating jub-effort.txt to account for recent test
class renames in titan05.  Some old classnames still linger in this
file and need to be updated in future commits.
