upgrade to sea-orm 0.12 and fix code

[keithamus]

Hey @mgugger, I tried to use this project with sea-orm 0.12 and got some errors due to a double reference on .contains. When trying to fix it I noticed that sea-orm 0.12 also dropped the default Display implementation for DeriveActiveEnum, which means Display needs to either be manually implemented, or you can use the fallback DeriveDisplay which re-introduces the old derived trait, so I've altered the enums in the example code to add DeriveDisplay which gets the code compiling.

Itertools was also out of date so I updated that, no other changes needed to be made for that though.

This was the main error;

Some errors have detailed explanations: E0277, E0599.

Once the main error was fixed I got errors about these.

Which lead me to SeaQL/sea-orm#1726 where I saw that they pulled out the default Display impl.
