Title: Fix Travis build

Force `bundle install` in install step

Travis will now runs `bundle install --deployment` if it detects that
the project has `Gemfile.lock`. However, there's a problem in Bundler
deployment install that cause it not installing `bundler` gem into
`vendor/bundle` directory, which causes `require 'bundler'` to fail.
