Fixed bug #19396: a crash for a an outer join operation

Browse source 
over two views when using syntax with curly braces.
Each outer join operation must be placed in a separate
nest. This was not done when the syntax with curly braces
was used. In some cases, in particular, for queries with outer
join operation over views it could cause a crash.
