get calls ignore params when being cached

[homj]

Steps to reproduce

As described in #92, the internal caching is flawed, even when using listStrategy: 'always'.
Additionally to the issue with find, this also affects get calls:

The hash value used to cache responses is based solely on the id and ignores params. This leads to problems, when using client side params to e.g. populate different fields on get calls.

Expected behavior

get calls with different params should result in actual new calls to the backend

Actual behavior

get calls with different params return a cached response when an existing call for the same id exists

System configuration

Backend uses params on get requests to populate different fields
