Rename Computer Issue: Naming Scheme Tokens Using last n characters

[Rocketman-Chris]

Summary:
Naming Scheme Tokens don't work when using the :-n token without defining a :wX:Y token

Steps to Reproduce:
If you run rocketman RenameComputer --computerName %=UDID:-7% it returns the result Data info doesn't have =UDID:-7 information

If you run rocketman RenameComputer --computerName %=UDID:w1:-7% it is able to change the name

Also, if you run rocketman RenameComputer --computerName %=UDID:7% or rocketman RenameComputer --computerName %=UDID:=7% it renames the computer correctly
