Fix failing test for edge gemfile option

[carlosantoniodasilva]

This should fix the build for 3-2-stable branch.

I added this testcase for fixing #4749.
I'm confusing... Why should we use 3-2-stable when using --edge option ?

related to #4912

[carlosantoniodasilva]

@kennyj hm yeah, I didn't check it further, just added the test fix. Seems like the :branch shouldn't really exist, let me check it better.

[guilleiguaran]

This confusing, generating a new app passing --edge option using 3.2.x also generate apps with conflicts about dependencies.

[carlosantoniodasilva]

Yeah, but with the :branch option:

gem 'sass-rails',   :git => 'git://github.com/rails/sass-rails.git',   :branch => '3-2-stable'
gem 'coffee-rails', :git => 'git://github.com/rails/coffee-rails.git', :branch => '3-2-stable'

I get the same error as result:

Bundler could not find compatible versions for gem "railties":
  In Gemfile:
    sass-rails (>= 0) ruby depends on
      railties (~> 3.2.0) ruby

    rails (>= 0) ruby depends on
      railties (4.0.0.beta)

If I remove the :branch, it bundles successfully.

I get same result when I was tackling #4749.

BTW, My confirmation way is kennyj@8bf3c6d#commitcomment-921532
