Search for *psdeploy.ps1 is case sensitive on Unix systems

[vexx32]

Coupled with the fact that the error message mentions it can't find any .PSDeploy.ps1 files in the given location, the -Filter is applied as *undeployed.ps1, which can break the ability to do deployments unexpectedly, with very little information as to what's actually going wrong.

Given that you're only searching a single directory (I think?) It is probably fine to instead use a Where-Object filter or an -Include filter instead (not sure if those are case sensitive on Unix systems, but I would suspect not, given they're done by the cmdlets and not the filesystem itself?)
