Change version of pheonix so that it does not conflict with Erlang 1.9, and fix test

[tomfbiz]

Running the tests with Erlang 1.9 was generating compile errors:

crash reason: {case_clause,
    {'EXIT',
        {badarg,
            [{erl_anno,anno_info,[-1],[{file,"erl_anno.erl"},{line,360}]},
             {v3_core,record_anno,2,[{file,"v3_core.erl"},{line,2410}]},
             {v3_core,expr,2,[{file,"v3_core.erl"},{line,539}]},
             {v3_core,safe,2,[{file,"v3_core.erl"},{line,1593}]},
             {v3_core,expr,2,[{file,"v3_core.erl"},{line,528}]},
             {v3_core,safe,2,[{file,"v3_core.erl"},{line,1593}]},
             {v3_core,'-safe_list/2-anonymous-0-',2,

             {lists,foldr,3,[{file,"lists.erl"},{line,1276}]}]}}}

Changing versions of phoenix and elixir fixed the issue

Also had to change the order of modules in test\presenter_test.exs to prevent this error:

** (UndefinedFunctionError) function TestAddictUserAssociationsSchema.__struct__/0 is undefined
(module TestAddictUserAssociationsSchema is not available)

Made changes to sample application per instructions here:
#Phoenix 1.1.x to 1.2.0 Upgrade Instructions

I added changes to make the sample app test run as well.

I see this PR has been hanging around for a long time -- any suggestions of how to improve this so it could be merged?

Maybe an upgrade to Phoenix 1.3 would be more useful?
