Empty resolution precedence layer throws error

Conditional entries in the resolution precedence throw an error:

ResolutionPrecedence:
  - AllNodes\$($Node.Environment)\$($Node.NodeName)
  - Environment\$($Node.Environment)
  - Locations\$($Node.Location)
  - Roles\$($Node.Role)
  - Baselines\Security
  - Baselines\$($Node.Baseline)
  - Baselines\DscLcm
  - |
    '[x= {
      if ($node.Name -notlike "*file*")
      {
        'Somevalue'
      }
      else
      {
        #nothing
      }
    } =]'

The error is:

System.Management.Automation.ParameterBindingValidationException: Cannot bind argument to parameter 'Path' because it is an empty string.
   at System.Management.Automation.ExceptionHandlingOps.CheckActionPreference(FunctionContext funcContext, Exception exception)
   at Resolve-Datum(Closure, FunctionContext)
   at System.Management.Automation.PSScriptCmdlet.RunClause(Action`1 clause, Object dollarUnderbar, Object inputToProcess)
   at System.Management.Automation.CommandProcessorBase.Complete()

Reproduce the error with the ResolutionPrecedence YAML shown in the issue, then start at the Resolve-Datum entry point named in the stack trace. Trace how the conditional expression produces an empty value and how it is passed to the Path parameter. Done means an empty resolution-precedence layer no longer raises the parameter-binding error.
