Fix assertion failure in TransformOpaqueValueExpr
Summary:
`OpaqueValueExpr`s may not have a source expression (as in the case when
they are created due to a default argument error).
This can cause an assertion failure in `TransformOpaqueValueExpr` during
template instantiation.
This patch fixes the assertion failure.
