Dove test broken on 1.6 when Diem specific code is referenced

[villesundell]

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,

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.
