* fixes tests by coercing the `test-unzip` return value back into a valid path string

.# Discussion
For Win10 machines, `test-unzip` returns a bugged value, causing test failures.
Investigation shows that the combination of Pester, COM (used within unzip_old), and
Win10 leads to the odd/bugged return value. The return value contains the correct
string, but it is prefaced with a leading space which arises de-novo during the
execution return process from `test-unzip`. The value is correct and usable at the end
of `test-unzip` but is bugged upon receiving the value at the caller. Removing the COM
call from within `unzip_old` or using a Windows version earlier than Win10 fixes the
problem, but are obviously not useful as solutions.
Given the nature of the returned value and COM involvement, the real problem is likely
stack corruption. But it's not clear whether the issue is with Pester, Win10/PowerShell,
or possibly even some subtle bug within unzip_old.
This, admittedly hacky, coercion fixes the problem for all Windows versions and also
keeps Appveyor satisfied.
* Scoop-Alias: remove erroneous output from dot-sourcing the source file
* Scoop-Alias: using "TestDrive:\" for mocked shimdir
- reduced cleanup
- improved robustness; excution is now independent of CWD
* Scoop-Core: corrected directory location code
- improved robustness; execution is now independent of CWD
Migrate unzip_old tests to pester
Migrate packages tests to Pester
Migrate opts.ps1 to Pester
Migrate tests to use Pester idiomatic tests
Move tests.ps1 to Scoop-TestLib.ps1
