Improve AST recovery for a TryStatement where the resource is missing a declared type. This is not a dup of bug 340837 (that one is about a complete absence of a TryStatement node).

    void foo() throws IOException {
        FileReader reader0 = new FileReader("file");
        writer0 = new FileWriter("out");

        try (FileReader reader = new FileReader("file");
                writer = new FileWriter("out")) {
            int ch;
            while ((ch = reader.read()) != -1) {
                System.out.println(ch);
            }
        }
    }

The 'writer = new FileWriter("out")' currently gets these errors on the second (incorrect) resource declaration:
- writer cannot be resolved to a type
- Syntax error on token "writer", VariableDeclaratorId expected after this

=> Would better be 'writer cannot be resolved to a variable', like for 'writer0'.

The AST would better also consider 'writer' as variable name and the type as missing.

Note: If I remove the type of 'FileReader reader' as well, then the recovery completely breaks down, and TryStatements has no resources any more.
