Move last 10 remaining CTF tests into ctf.jdo.tc7x package
FYI, I already committed two patches that rename the tables for all JDO CTF tests in the ctf.jdo.tc8x and ctf.jdo.tc9x packages. That leaves just the ctf.jdo.tc7x package to be done ....
Initial patch, renaming all tables to names with a tc7x prefix, initially for mySQL only.
Final (tested) patch.
