Catch clauses should (maybe) not be enclosed by their try stmt

[intrigus-lgtm]

Description of the issue
CodeQL models CatchClauses as being part of TryStmts.
I personally find this counter-intuitive since the {} braces of the try {} block do not enclose the catch() {}in any way.

try {
} catch() {
}

Here catch(){} would be enclosed by try {}

import java

from CatchClause c, TryStmt try
where c.getEnclosingStmt() = try
select c, try
