pythonPackages.graphite_api: move expression

According to the current convention python packages should live in
`pkgs/development/python-modules`. As I altered the `graphite_api`
expression previously in d3d1b888737 I decided to move it as well.

Additionally I applied some minor refactorings:

* use `fetchFromGitHub` instead of `fetchgit`.

* use `checkInputs` for test dependencies

* got rid of fixed points

* applied patch which supports flask-caching to 1.3.1 using `git apply
  -3`
