Inject class with no empty constructors from other module failed.

[baijianhua]

Define a class like this, and inject it in classes, if this class is in the same app module, it will success, but if move this class to a library module, it will fail. Exception is:
com.google.inject.CreationException: Unable to create injector, see the following errors:

1. Could not find a suitable constructor in com.lenovo.shareit.Test1. Classes must have either one (and only one) constructor annotated with @Inject or a zero-argument constructor that is not private.
   at com.lenovo.shareit.Test1.class(Unknown Source)
   while locating com.lenovo.shareit.Test1
   for field at com.lenovo.shareit.ShareitApp.test(Unknown Source)
