Thunder Wave + Normalize Fixes

Normalize should occur before Ion Deluge. So a Delcatty using Thunderwave with Ion Deluge active gets treated as an Electric Move (Tested against a Rhyhorn and a Misdreavus). Tested this one myself in game.

Also, Thunder Wave should be affected by type immunities in inverted. The reason for the change before was the test that was performed in game was against something with Lightning Rod, so it wouldn't paralyzed regardless of battle mode. This inadvertently broke Normalize Thunder Wave, which was report this morning as a bug. Wriggle did the testing for this section of the fix.
