Truncate environment stack on non-caught native error

[HalidOdat]

When an native error is thrown and not caught it only truncates the value stack, the environment stack is not changed this causes panics if we run code than access the environment.

For example

with (new Proxy({}, {has: p => false})) {a}

Running this code twice causes a panic (boa file.js file.js).
