fixed #2747 and a number of other error scenarios like wrong module names

[jurgenvinju]

• fix the actual NPE by coupling the URI to the ModuleEnvironment as soon as possible
• make sure users of theutil::EvalAPI can detect module load errors (it can not anymore due to the lazy reporting of module load errors introduced recently), note that util::Eval does not offer file watching, so we have to simulate reloading by re-importing.
• write some tests for module loading and reloading using the new util::Eval
  1. import a module with a parse error, fix it, re-load
  2. import a module with a broken module name. fix it, re-load
  3. import a non-existing module, create it, re-try
  4. import a correct module, introduce a parse error, re-load, fix the parse error, re-load
  5. etc.

I didn't do the "etc." but more tests can be added easily based on this framework.
