Remove all redundant std::move()s. I've also removed calls to
std::move() in tests, even if they act as an optimization. This is for
two reasons:
(a) Performance is not important for testing, and this helps with
readability.
(b) A whole bunch tests were relying on std::move() clearing vectors so
they can be repopulated and used again. This is undefined behavior:
> Objects of types defined in the C++ standard library may be moved from
> (12.8). Move operations may be explicitly specified or implicitly
> generated. Unless otherwise specified, such moved-from objects shall
> be placed in a valid but unspecified state.
All of these UB cases have been fixed.
Removed all duplicate variables left over from:
`auto* foo_ptr = foo.get()`
which became:
`auto* foo_ptr = foo`
