[CONTRACTS] implement register and is_registered tests

[0xChqrles]

The tests are already defined in src/components/registry/registry_test.cairo. You just need to write their implementation following the way the escrow tests are implemented.

These contracts will be holding funds, so it's of utmost importance that the tests cover 100% of possible use cases, are readable, easily modifiable, and consistent.

To better understand how the contracts work, please read this article How to manage liquidity in a P2P ramping app
