Title: chore(angular.module): improve the 'No module' error message

Whether or not the 'requires' parameter of 'angular.module' is optional
depends on the state of the application. The thrown error message is
not very descriptive and can be improved. For instance, the error
could contain a hint that the parameter is required for initial
module creation.

The improvement is based on comments under the angular.module documentation.
