Provide the steps to reproduce

1. Configure lighthouse to run with custom throttling settings, mark the throttling method as devtools, mark the emulatedFormFactor as "none"
2. Run LH on [any url]
3. Load the report JSON into lighthouse-viewer

What is the current behaviour?

• The network throttling summary is hardcoded to "Throttled Slow 4G network"
• The device summary is hardcoded to "No emulation"
• The device summary, is technically correct (emulated form factor set to none), but the other configuration options for emulatedFormFactor (mobile, desktop) will result in a hardcoded value of either "Emulated Nexus 5X" or "Emulated Desktop"

What is the expected behaviour?

• Network throttling summary should describe the network settings used
• Device summary should describe the device used
