Fix getting device following enumeration when RealHardwarePort is not set

[josesimoes]

Description

• Setting the device local var was failing because of a wrong if clause.

Motivation and Context

• If RealHardwarePort is not set (or empty) in the run.settings file, a device discovery is performed. Following this, provinding that devices are present, the 1st one from the list should be target and set as the device. The if clause was wrong failing to set that device local var which caused a null exception right out of the gate when starting the execute tests section.

How Has This Been Tested?

• Running the PoC test app.
