vala: Set is_yield_expression in async context when chaining up to async base ctor

vala-CRITICAL **: vala_member_access_get_inner: assertion 'self != NULL' failed
vala-CRITICAL **: vala_member_access_get_member_name: assertion 'self != NULL' failed

Avoid these spurious criticals and trigger the currently expected error.
