Fix for usage with a beta or rc version of rails

[colinux]

For beta/rc versions of Rails, find_by_name does not return the rails gem. By using the less strict find_all_by_name method, this allows using i18n-js with versions of rails like 4.2.1.rc1.

The code can already detect beta/rc versions of rails gem
try I18n::JS::Dependencies.send(:safe_gem_check, "rails", "~> 4.0", ">= 4.0.0.beta1") with 4.2.1.rc1 installed

Hello,

if I replace the line 10 (method rails4?) with safe_gem_check("rails", "~> 4", ">= 4.0.0.beta1") && running_rails4?, it doesn't work neither, the rcX are not detected. Same result with safe_gem_check("rails", "~> 4", ">= 4.0.0.beta1", ">= 4.0.0.rc1").

Gem::Specification.find_by_name("rails", "~> 4.0", ">= 4.0.0.beta1")? I can confirm this works and detects rails 4.2.1.rc1.
If this still doesn't work try changing the arguments passed inside and report back what works for you.
You can try Gem::Specification.find_all_by_name("rails", "~> 4.0", ">= 4.0.0.beta1") first.

Oooh I just have realized I run i18n-js in 3.0.0.rc8 version, not the master. The master code works perfectly well without any change, you are right. Sorry for the waste of time !
