Title: yesod-persistent: workarount tests build failure

Test failed to build as:

> test/Yesod/PersistSpec.hs:16:1:
> Illegal instance declaration for ‘ToBackendKey SqlBackend Person’
> (All instance types must be of the form (T t1 ... tn)
> where T is not a synonym.
> Use TypeSynonymInstances if you want to disable this.)
> In the instance declaration for ‘ToBackendKey SqlBackend Person’

Might not be the best fix, please check if it makes sense.
