Get-SoftwareStats sends empty string with the list of processes.

[pfaffle]

In Get-SoftwareStats, when creating the list of running processes, a process named the empty string is incorrectly included in the list and subsequently sent to Graphite.

Preferably, this should be fixed by altering the algorithm used to create the list so it never gets added in the first place.

Failing that, it would be acceptable to simply remove the empty string(s) from the list after the fact, or implement logic to not send a line if the process is named the empty string.
