Exception thrown during "Find Usages" when catch statement uses a literal expression instead of a code block.

[EricBishton]

When doing a "find usages" on "String", the following exception is thrown when cpp_std\EReg.hx, line 124, is processed. (Haxe version 3.4.7, plugin at 1.2 release candidate.)

java.lang.Throwable: Code block not found among parameter' (PARAMETER 'e' "e : String") parent' (CATCH_STATEMENT "catch( e : String ) null;") children: [PARAMETER 'e' "e : String", LITERAL_EXPRESSION "null":null:HaxeLiteralExpressionImpl]
