Does not initialize properly on PowerShell Core

[mpodwysocki]

Using PowerShell Core, currently version 6.1.1, z does not initialize properly with the following error:

Cannot index into a null array.
At C:\Program Files\PowerShell\Modules\z\1.1.9\z.psm1:655 char:1
+ $global:options['CustomArgumentCompleters']['z:JumpPath'] = $Completi ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo          : InvalidOperation: (:) [], RuntimeException
+ FullyQualifiedErrorId : NullArray

Reproduction Steps:

Install-Module -Name z
Import-Module z

Workaround steps is to initialize the dictionary properly for the CustomArgumentCompleters:

if (-not $global:options['CustomArgumentCompleters']) { 
  $global:options = @{CustomArgumentCompleters = @{}} 
}

What should be the proper answer here?

This does not happen for "normal" Powershell. I also do not have Powershell Core installed. Happy to accept a pull request for this :)

There are no issues with current z and PS Core 7
