Revert "[IDE/CodeCompletion] Minor enhancement, abort all-visible-modules visitation if we already handled that particular ImportedModule."
Revert "[IDE/CodeCompletion] Minor enhancement, abort all-visible-modules visitation if we already handled that particular ImportedModule."

This reverts commit r18426.
Per feedback from Jordan this does the wrong thing because it aborts the entire visitation, not just the current visitation path.
