First thing: if you think that is your seed and your password, it's a really bad idea to be posting it on the Internet. Luckily for you, it seems it's not.

I don't really understand the chain of events you described, but the "seed" you posted above is definitely not an Electrum 1.x seed (and it's too short for a normal Electrum 2.x seed).

It can be decrypted with the seed_password you posted using Electrum's kdf and cipher, and the result is "This is just a test for AES decryption!", but as an Electrum seed it's meaningless, so I couldn't say where it came from.
