Don't join fkey table when linq comparison with composite id

[jeff-hagen]

When referencing a foreign key composite-id in Linq, don't add a join with the fkey table to the resulting SQL (make behavior consistent with the same query in HQL). Fixes #3676

@fredericDelaporte would you mind taking a look at my PR?

About *.sql files, file encoding changes are not encouraged. They are harder to review and break somewhat the history when looking for significant changes.

This said, as the encoding was not consistent with the 2012 files, let it be.

LGTM.
