(ITS#8310) LMDB cursor_del followed by MDB_NEXT can trigger assert crash

This seems to be a variation on ITS#8258 - the base cause is the same; an
mdb_cursor_del causes the tree to grow in depth, the cursor is not updated with
the new depth, and the next cursor op on the cursor asserts.
I have a DB and short C file which triggers the assert in a simple manner.
