Fix partial compile regression introduced in 10.0-RC5 (#653)

10.0-RC5 introduced a regression that stops "Partial Compilation" from working.
This is due to the ProcessingContext.isInjectModule() not correctly detecting
the current module. This meant no existing module was found, no dependency
meta data for the module was read, a new module is created for the components
included in the partial compile and generally that will fail with missing dependencies.

A workaround is to perform a full compile (but this isn't really a workable
solution - its important that partial compile works).
