Another attempt to fix bug mdev-5103.
The earlier pushed fix for the bug was incomplete. It did not remove the main cause of the problem: the function remove_eq_conds() removed always true multiple equalities from any conjunct, but did not adjust the list of them stored in Item_cond_and::cond_equal.current_level. Simplified the test case for the bug and moved it to another test file. The fix triggered changes in EXPLAIN EXTENDED for some queries.
