Dove test broken on 1.6 when Diem specific code is referenced

Hello, fellow Move soldiers! We continue marching on, despite the negative news lately. Glad to see 1.6 being released nevertheless :tada:

The previous issue with dove test that was fixed in 1.5.6 (#180) reincarnated in 1.6.0-86817ac.

The test problem being:

┌── test_wrap ──────
│ ITE: An unknown error was reported. Location: 
│ VMError (if there is one): VMError {
│     major_status: UNEXPECTED_VERIFIER_ERROR,
│     sub_status: None,

I don't think this problem is related to named addresses. 1.6.0 right now doesn't support Diem-specific native functions, like ones found in DiemAccount, I assume you're trying to use DiemAccount::create_signer().

As a workaround, you can try Pontem-specific one from here https://github.com/pontem-network/pont-stdlib/blob/master/sources/PontAccount.move#L440 if that fits your case.

I'll get back to you later regarding support for DiemAccount::create_signer() and others.
