refactor tests

[andreineculau]

to get around these annoyances:

• put together constructs related to one test, so that you can read assertion, mocked request, mocked apib (not jump through the file, or have 3 buffers opened just to have the full view of 1 test). Possibly go as far as 1 test module per test (more copy-paste boilerplate, but who cares)
• if a test fails today, the output is truncated (ellipsis)
• TBC

Don't beat me but would it be so bad to do the "meck:expect" in each test itself respectively?

katt_run_basic(lhttpc_request) ->
  fun( "http://127.0.0.1/step1" = _Url

                   , _Headers

the location of the created example.
