Don't check for publisher in vsce package

[vojtechkral]

Fix #328

This is quite an annoying bug when one wants to publish a private / organization-internal extension to co-workers...

I fixed it in a really simple way, not sure it this is good enough...

In fact, it's not. Just removing the function causes VS Code to error out with Cannot read property 'toLocaleLowerCase' of undefined.

Not sure what to do about that...

@vojtechkral I am building an independent packager and stumbled upon this. Apparently the function installFromVSIX https://github.com/microsoft/vscode/blob/a416c1534bb9159c7ad9d88f19d70019ded16a6a/src/vs/workbench/contrib/extensions/browser/extensionsWorkbenchService.ts#L1032) uses a field 'publisher' from the extension. If you add the field 'publisher' into the package.json like this

{ "publisher": "test", "name": "something",

vscode will recognize this as the publisher and properly register the extension.
