or {} is ignored for map on appending value to array

[gechandesu]

Describe the bug

The variable does not take a value from the or {} block before being added to the array.

Reproduction Steps

module main

fn main() {
	foobar := {
		'foo': 'Foo'
		'bar': 'Bar'
	}
	mut arr := []string{}
	arr << foobar['foo']
	arr << foobar['baz'] or { 'Unknown' }
	// I expect ['Foo', 'Unknown'] but got ['Foo', '']
	assert arr == ['Foo', 'Unknown']
}

Expected Behavior

Assertion passed

Current Behavior

~ $ v run v_issue.v
v_issue.v:12: FAIL: fn main.main: assert arr == ['Foo', 'Unknown']
  left value: arr = ['Foo', '']
  right value: ['Foo', 'Unknown']
V panic: Assertion failed...
