Check whether `Rails.application` defined before calling it 

In #27674 we changed the migration generator to generate migrations at
the path defined in `Rails.application.config.paths` however the code
checked for the presence of the `Rails` constant but not the
`Rails.application` method which caused problems when using Active
Record and generators outside of the context of a Rails application.

Fixes #28325.
