Don't use Gemfile in test application in railties

Option to run `bundle install` after generating new appplication was
added recently to rails. Since introduction, it contained a subtle bug
that caused it to use `Gemfile` from current directory (if it exists)
rather than from generated directory. This also accidentaly caused
railties tests to work without any problems - after generating test app
it just used `Gemfile` from the repository, rather than the one in
generated app. After fixing the bug mentioned above, this of course
broke. The easiest way to bypass that is to not generate a `Gemfile` for
test application - with such setup Bundler will just use first available
`Gemfile` in one of the parent directories.
