Added credential parameter to subsequent calls of Publish-Module/Script.

[dotps1]

This is needed when a module is published that has the RequiredModules attribute in the manifest, and is being published to a Repo that does not have Anonymous access because the required module lookups will fail because there is no read access to repo.

for the life of me i cannot figure out why the Script tests are failing with:

Publish-PSArtifactUtility : A parameter cannot be found that matches parameter name 'Credential'.

i will continue to look tonight, but this change needs to happen.

[dotps1]

and the issues continue! OneGet/oneget#270

= $null [](start = 19, length = 8)

What is the need for specifying the default value? #Closed

[bmanikm]

$Credential = $null [](start = 8, length = 19)

Please avoid parameters with $null as default values.
#Closed

[dotps1]

I have removed the default values. I swear there used to be a PSScriptAnalyzer rule that was like PSAvoidUninitalizedParamerterValues or something like that where basically if the parameter was not Mandatory, then it needed a default value. I suppose this would have worked as well:
Credential = [PSCredential]::Empty

Thanks.
