Switch statement without reached the case block

Hi everyone,
there is an inconsistency in Chakra if a switch statement with only one case block evaluation that could be not reached.

version: 1.10.2
OS: Ubuntu 16.04 x64

steps to reproduce:
```js
{ function f() { return "f 0"; } }
switch (1)
{
case /0.0/gi:
function f() {
return "f 1";
}
break;
}
print( f() );
```
Actual results:
f 1

Expected results:
f 0

if we try to add the default block (`default: ` or `default: break;`), the same occurs as above.

V8 and SpiderMonkey works as expected.
