unknown 9a02fede24 Fixed bug #18279: crash in the cases when on conditions are moved ...

out of a nested join to the on conditions for the nest.
The bug happened due to:
1. The function simplify_joins could change on expressions for nested joins.
   Yet modified on expressions were not saved in prep_on_expr.
2. On expressions were not restored for nested joins in 
   reinit_stmt_before_use.
