getProjectModules: IllegalStateException
In my project, we have multiple modules, some of which also contain other
modules.
When building one specific module (which itself had child modules) from the
root pom file, the build would fail when maven-assembly-plugin threw an
IllegalStateException, but building from the module's pom.xml file directly,
the build succeeded.
I narrowed this down to the candidateIterator being set to null after
.remove() is called, and that iterator not being updated to the next item
before using it as a candidate for other projects.
This change ensures that after removing the item from the iterator, that we
move to the next item before doing anymore comparisons.
This is the stacktrace from the maven-assembly-plugin failure:
```
